Lime is the new salt! This recipe uses lime juice for flavor instead of salt, which is not a heart healthy ingredient.
Combine lime juice, 1 tablespoon balsamic vinegar and garlic in a bowl. Season fish with freshly ground pepper and let stand in marinade for 10 minutes on each side in the refrigerator. With clean hands, rub 1 tablespoon olive oil onto both sides of fish. Heat a nonstick skillet to very hot and almost smoking. Add tuna to pan and sear until desired doneness. Flip with a spatula and sear the other side. Remove immediately. Slice tuna with a very sharp knife into thin slices. Combine all vegetables and herbs in a bowl and toss with 5 tablespoons balsamic vinegar, 2 tablespoons lime juice and remaining olive oil. Serve salad in radicchio leaves and top salad with cheese and ahi tuna slices.

Chef’s Note: This recipe allows for one tablespoon feta cheese per person. This is a wonderful ingredient to use in moderation because it has big flavor and only requires a small portion.
