In small saucepan combine ketchup, water, chopped onion and brown sugar. Stir in lemon juice, cooking oil, prepared mustard, Worcestershire sauce and chili powder. Simmer, uncovered, 10 minutes stirring once or twice. On six short skewers, thread steak pieces alternately with shrimp, zucchini, corn, onion wedges, and pepper squares. Grill kabobs over medium-hot coals until meat is desired doneness, allow 15-17 minutes for medium rare. Turn kabobs often, brushing with sauce. Garnish end of each skewer with a cherry tomato. |
