Tuna contains the omega-3 oil valued by many; some tuna can contain as much as 300 mg per serving. Tuna is an oily fish that also contains a high amount of vitamin D. The fish can be seared, baked, grilled, smoked or pan fried. It can be cooked rare and served in a variety of styles. Tuna is an alternative to other seafood and red meat.
Pour the lemon juice onto the tuna steak and set aside for 15 minutes.
Melt the butter in a skillet on medium. Add salt, pepper and garlic to the pan.
Place the tuna steak in the pan and cook to desired doneness. Cut the tuna in the centre and see how much red is present. The centre should be slightly red, because the tuna will cook a little longer once it is taken off the heat. Do not overcook.
Remove the tuna from the heat, and let the tuna sit for five minutes.
Serve with parsley as a garnish.
Try flavours other than lemon if you desire.
Make sure your fish is fresh for the best results.
