2 lb. sirloin steak
1/2 c. soy sauce
1/2 c. rice vinegar
1/3 c. honey
1 tsp. ground pepper 
1 tsp. ground ginger 

Combine all ingredients except the steak in a small bowl. Mix well. Pour out and reserve 1/2 cup of the marinade. Place the steak in a gallon-size food storage bag, and pour the marinade over the steak. Seal, and set aside at room temperature for 1 hour, or refrigerate for up to 2 hours. Turn the bag over every 15 minutes or so to fully distribute the marinade.

Prepare the grill. Spray lightly with nonstick cooking spray.

Grill steak about 8 minutes per side, basting every so often with reserved marinade. Check for doneness by making a cut into the thickest part of the steak. Leave on for a few more minutes, if desired.

Remove steak from grill, and let sit about 3 minutes before slicing. Serve immediately.
