George's Lowfat Grilled Tuna
Ingredients:

2 six ounce tuna steaks
4 oz. white wine
2 oz. extra virgin olive oil
salt to taste (I prefer Kosher for grilling)
Pepper to taste
Garlic powder to taste
1 Tsp. rosemary

Preparation

In a medium bag (or covered dish) combine the wine, oil, salt, pepper, garlic and rosemary.

Stir well then place your tuna steaks in the marinade for 30 minutes to an hour.

Tuna is very easy to break apart.  Be cautious handling the fish.

Place on a grill at medium high heat.

For medium-well, plan on about 5 minutes per side.

Enjoy.
