Tomato stuffed with Mozzarella, Basil, Avocados, Balsamic Vinegar, Olive Oil and a dash of Salt & Pepper.  Sesame and Ginger Glazed Tuna Steak is its perfect pairing.  This was one of those spare of the moment thoughts that came to me, and the creation turned out amazing.  I hope you like!!  (Note: that the glaze will darken when cooked, as seen above)

Tuna, like other fish, is full of omega-3 fatty acids. These help to eliminate  erratic heart beats, and that lowers the risk of blood clots and heart attacks.  Since eating tuna helps prevent blood clots and also improves blood flow, it can  help prevent strokes. Eating only 1 to 3 servings a month is enough to lower the  risk of stroke in a person. The omega-3 count in tuna is greatly beneficial to skin care. It helps to reduce inflammation, which helps  reduce the risk of sunburn and skin cancer.  Tuna is a good source of selenium as well as omega-3. This is important in liver  health, which helps to promote detoxification of the body.
