1 ¼ pounds Skirt, flank, or lean sirloin steak
1 cup Balsamic vinegar
2 tablespoons Chopped onion
Salt to taste
Black pepper, freshly ground to taste
Step 1- Preheat a gas grill or broiler for 10 minutes, or start a charcoal fire 30 minutes ahead.
Step 2- Remove fat from meat. Place in a bowl or plastic bag with vinegar and onion. Let marinate 20 minutes. Drain and place on a hot grill or under a preheated broiler. For rare, cook 5 minutes if steak is thin or 8 minutes if thicker. Cook longer if you like it medium or well done. Remove to a cutting board, cover with foil, and let rest 5 minutes. Slice on a diagonal against the grain.
