1/2 env. dry onion soup mix
2 tbsp. sugar
1/2 c. ketchup
1/4 c. vinegar
1/4 c. salad oil
1 tbsp. prepared mustard
1/4 tsp. salt
1/2 c. water

Combine all ingredients in a saucepan. Heat to boiling. Simmer 15 to 20 minutes. (Caution: This mixture smells awful while cooking but don't let it deceive you). Let beef soak in marinade in the refrigerator for a few hours (stirring once). Cook on grill or broil.
