Two sauces you may use:

One is made of fresh squeezed orange juice and fresh lemon juice. Half and half, you decide on the quantity of juice according to the amount of beef so that it will be juicy. Add salt to taste and slices of white onions. Marinade in a closed container for at least 1 whole day prior to use. Turn the beef from time to time to allow the juices to blend.

The second sauce is more commonly used. 1 c. tomato sauce (8 oz. can) 1 c. prepared BBQ sauce 2 tbsp. lemon juice 1 tsp. garlic powder 1 tbsp. minced onion 1/2 tsp. dry mustard (opt.) 1 tsp. black pepper 1 tbsp. Worcestershire sauce 1 tbsp. oil

Combine all ingredients, mix well and let stand for a few minutes for flavors to blend. Marinate beef strips as described above. Yield: about 3 cups. Grill meat strips over glowing charcoal. Serves 8 to 10 persons.
