1 cup ketchup
1/4 A-1 Steak Sauce
1/3 cup firmly packed Splenda brown sugar blend
1/2 cup apple cider vinegar
2 tbsp Worcestershire sauce
2 lb boneless top sirloin, trimmed and cut in 32 chunks
1 green bell pepper, cut into 16 pieces
1 red or orange bell pepper, cut into 16 pieces
Combine the ketchup, steak sauce, Splenda, vinegar, and Worcestershire sauce in a medium saucepan; bring to a boil over medium heat. Stir occasionally and cook until the Splenda is totally dissolved. Remove from the heat and allow to cool.
Onto each skewer alternately with a piece of steak, a piece of red pepper, a piece of steak, a piece of green pepper, and repeat so that each skewer has 4 pieces of steak, two pieces of red pepper, and 2 pieces of green pepper. Place skewers in a 9 x 13-inch glass baking dish; pour the cooled marinade over the skewers. Cover with foil and refrigerate from 2 hours to overnight.
Preheat broiler to high and coat a rimmed baking sheet with nonstick cooking spray (or grill kabobs). Place kabobs on the baking sheet or grill, discarding an excess marinade. Broil or grill about 15 minutes or until meat reaches the desired doneness. Turn at least once during cooking.
