1 1/2 c. white wine
1/2 c. vinegar
1 c. soy sauce
4 tbsp. sugar

Score roast 1/4 inch deep on both sides approximately 1 inch apart. Let it set at room temperature 1/2-1 hour before seasoning. Rub garlic (to taste) on both sides. Sprinkle with salt, squeeze fresh lemon juice on both sides. Pepper heavily. Pour 1/2 of marinade over meat. Let set for 15-30 minutes. Sear meat on both sides. Remove and cover with foil and remaining marinade. Cook for 20 minutes or more (time depends on BBQ, 20 minutes on a Weber). Slice and eat.
