1/4 cup soy sauce1/2 cup dark brown sugar2 tablespoons olive oil3 cloves garlic, minced or crushed1/2 teaspoon ground ginger1 1/2 to 2 1/4-pound piece of London Broil
Measure soy sauce in a 2-cup measuring cup. Add sugar, olive oil, garlic and ginger and stir until sugar is dissolved. Put meat into a heavy-duty zipper-top plastic bag and pour marinade into bag. Remove air from bag and refrigerate for 24-48 hours.
Remove meat from marinade (discard marinade) and grill meat until it reaches desired doneness for your taste buds; medium rare is perfect!
Remove from grill, let rest for 5 minutes, slice and serve.
