1/4 c. oil
1 sm. onion, peeled & chopped
1 clove garlic, peeled & chopped
6 tbsp. lemon juice
2 c. beer
2 c. chili sauce
1 tbsp. Worcestershire sauce
1 tsp. salt

Heat oil and saute onion and garlic until soft. Add lemon juice, beef, chili sauce, Worcestershire sauce and salt. Cook over medium heat for about 5 minutes or until sauce bubbles. Use sauce to brush on meat during grilling or as a delicious marinade. Cover thick chuck or round steaks completely with sauce and let stand for several hours, in refrigerator.
