Mix the beef, water chestnuts and green onions together.
Shape the mixture into 6 patties, each about 3/4-inch thick. Place the patties in an ungreased 10 X 6 X 1 3/4-inch baking dish.
Mix the remaining ingredients together and pour over the patties. Cover and refrigerate for at least 3 hours, turning the patties once.
Remove the patties from the marinade. Broil or grill the patties 4-inches from the heat, turning once, until the desired doneness is reached, about 10 to 15 minutes. Brush frequently with the leftover marinade.
Serve on buns or rolls with your favorite toppings.
