3/4 c. catsup
1/4 c. water
1/2 sm. onion, minced
1/4 c. melted butter
3 tbsp. lemon juice
1 tbsp. prepared mustard
3 tbsp. brown sugar
1 tbsp. Worcestershire sauce
1/2 tsp. chili powder
1 1/2 lbs. beef sirloin cut in cubes
1 lb. large shrimp, shelled
2 lg. zucchini, cut in 1 inch pieces
3 sm. onions
2 green peppers, cut in 1 1/2 inch squares
12 cherry tomatoes

Combine first 10 ingredients in a saucepan and simmer for 5 to 10 minutes. Parboil whole onions, then add zucchini and peppers and boil 1 minute more. Refresh under cold water. Thread beef, shrimp and vegetables alternately on 6 long skewers. Grill kabobs over medium hot fire, baste often with sauce. Grill 12 to 15 minutes for rare, serve with rice.

We cook our beef cubes in the microwave for a few minutes to make sure they are done. We also add potato cubes to vegetables.
