2 lb. beef (flank, round steak, fillet, or boneless sirloin)
3 tbsp. soy sauce
1 tsp. garlic powder
1 tsp. powdered ginger
Juice of 1 lime
1 tsp. sugar
1/2 c. vegetable oil

Place the beef in a mixing bowl. Combine the remaining ingredients and mix well. Pour over the beef and marinate in refrigerator for several hours or overnight. Remove the beef from the marinade and grill over hot coals. Turn often, brushing with marinade and cook to desired degree of doneness. Before serving, pour remaining marinade over the beef if desired.
