1/2 c. soy sauce
1/2 c. oil
1 tsp. garlic, minced
1 tbsp. ketchup
1/2 tsp. pepper
1 tbsp. vinegar

Make burger patties like usual. Mix ingredients beforehand and as the burgers are cooked, pour sauce on burgers as they are cooking, each side. Or you can also put the burgers in the sauce and place in refrigerator as a marinate. Cook burgers after they have marinated for 1 hour.
