- 2 (6 ounce) tuna steaks, about 1 inch thick
- 1 cup Italian-style salad dressing
- Place tuna steaks with Italian dressing in a bowl, coating both sides; marinate in refrigerator for 20 minutes.
- Preheat outdoor grill for medium-high heat, and lightly oil the grate.
- Grill tuna on the preheated grill until tuna lightens in color but retains a thin line of pink in the center, about 5 minutes on each side.
