The healthiest sandwich you'll ever eat!

Updated May 11, 2017

Take a moment to think about your perfect food. The criteria should be fairly short: Delicious, healthy and convenient. After all, you shouldn’t need a culinary degree to create a masterpiece that satisfies even the most fickle eater. Enter the sandwich. It almost fits the bill, except for the health aspect. You see, most sandwiches are often packed with artery clogging fats, refined sugars that disrupt your blood sugar, and enough calories to sink any healthy eating plan. But that’s all about to change. The truth is, with a little creativity the sandwich can be transformed into the perfect meal. Use these guidelines to help you rediscover the sandwich, and your waistline—and your taste buds—will never be more thankful.

One of my favourite cuts for steak sandwiches is top sirloin.’s a flavour sensation so good, your taste buds will wish they had taste buds.

The bread

Bread can make or break your sandwich -- it can also help make or break your health. Most of the breads lining the shelves of your supermarket are made with refined sugar that can increase your risk of obesity and heart disease.

For this uber-sandwich, use sprouted whole grain bread. Sprouted grain breads are minimally processed and contain low acting carbohydrates that will provide you with a consistent flow of energy for several hours, eliminating the late afternoon energy crash. If you can't find sprouted grain breads at your local supermarket, says Chris Mohr, a registered dietition and a frequent guest on TV to discuss nutrition. "Aim for a product with at least 3 g of fiber or more per slice." He explains that companies are adding fiber from non whole grain sources, making that number higher than it should be naturally. "So in addition to the 3 g of fiber, look for breads where the first ingredient on the nutrition label is 100 percent whole wheat flour with very few other ingredients listed," he adds.

The meat

The meat of choice for this healthiest ever sandwich may surprise you. It isn’t turkey or chicken breast. No, this ultimate sandwich uses beef. You may have heard that beef is bad for your health -- especially your heart health -- but a 2010 news release from the Harvard School of Public Health indicates that this isn’t the case if you make the right beef choices. Harvard researchers reviewed 20 studies that included more than 1.2 million people, to examine the relationship between red meat and deaths related to heart health. They found that people who ate one serving of processed meat per day had a 19 percent higher risk of developing diabetes and a 42 percent higher risk of having heart disease; however, eating unprocessed meat was not associated with an increased risk of diabetes or heart disease. The research suggests that differences in salt and preservatives, rather than fats, might explain the higher risk of heart disease and diabetes seen with processed meats, but not with unprocessed red meats.

So when preparing this exceptional sandwich, skip the processed meat and go for grilled top sirloin steak, one of the 29 cuts of beef most often referred to as lean. Lean beef has a nutritional package with which turkey and chicken have trouble competing. Top sirloin is an excellent source of zinc, vitamin B-12, iron and selenium. Beef also contains high levels of glutamate and glutamic acid, which directly simulate your umami taste receptors, the taste buds that are responsible for intense savory flavors.

The toppings

Add two slices of deep red, ripe tomatoes to your sandwich. Tomatoes are a source of vitamin C and lycopene -- and the riper the tomato, the more umami -- or savoriness -- it contains. The combination of top sirloin and tomatoes is a favorite of the executive chef for the National Cattlemen’s Beef Association, Dave Zino. “One of my favourite cuts for steak sandwiches is top sirloin. It’s not only good for you, but with all the umami you get with the synergistic combination of beef and tomatoes, it’s a flavor sensation so good, your taste buds will wish they had taste buds,” he says.

The next topping on your sandwich is sliced red onion. The potent flavour and deep purple colour of red onions comes from their quercetin. Quercetin is part of a family of antioxidants called flavonoids, which scientists believe may hinder production of fat cells and fight lung inflammation which causes asthma.

Finally, many sandwiches are topped with lettuce, but the deep green richness of baby spinach provides more vitamin K, vitamin A and calcium than your average leaf of lettuce and is, thus, a must for a a "healthiest ever" sandwich.

The toppings provide flavor as well as health benefits, so there's no need to add other toppings that could include extra fat and calories.

The spread

The final touch for this mouthwatering sandwich is the spread -- as no one likes a dry sandwich. You can probably guess that slathering on average condiments such as mayonnaise, mustard or ketchup won’t make the culinary cut for a "best ever" sandwich.

Instead, spread mashed avocado on each slice of bread. Avocado, commonly referred to as "poor man’s butter" just decades ago, is an unlikely source of fiber in this sandwich -- but one-half a Hass avocado contains approximately 6 g of fiber. You may have avoided avocados in the past because of their high fat content; however, the fat in avocados is predominantly monounsaturated fat.

Monounsaturated fats can lower your cholesterol levels and may help improve insulin sensitivity. Avocados also are a nutritional complement to the tomatoes. A study published in March 2005 in the "Journal of Nutrition" indicates that eating avocados with tomato products increases the absorption of the health promoting carotenoids from the tomatoes.

How to make the world’s healthiest sandwich

Now that you know what to put in this "healthiest ever" sandwich, you have to put it together. First, gather your ingredients, which include 4 oz. of top sirloin steak, 1 tbsp. of mashed avocado, 2 slices of toasted sprouted grain bread, 3 slices of ripe tomato and 6 to 8 leaves of washed baby spinach.

Warm the top sirloin to room temperature as this allows for more even cooking Season both sides of the steak with ½ tsp. of salt and 2 tsp. of black pepper. Then place it on a double sided electric grill for 5 to 7 minutes. When it is done grilling, let the steak sit for 5 to 7 minutes before cutting -- this will allow the juices to come back into the steak, yielding moister meat. While the steak is resting, toast the bread and spread 1 tbsp. of mashed avocado on each slice. Slice the top sirloin steak against the grain and then place the slices on one piece of toast. Top with tomato, red onion, baby spinach and the second slice of bread. Enjoy.
