4 cloves garlic, finely chopped
1 tsp. crushed red-pepper flakes
1/2 tsp. ground black pepper
1/2 tsp. grated lime rind
1/2 tsp. salt

Kabobs:
1 1/4 lb. boneless beef top loin or sirloin steak, cut into 1 1/4-inch-thick cubes

1 large red pepper, seeded and cut into 1-inch pieces
Twelve 8-inch wooden skewers, soaked in water 15 minutes

Small hot peppers (optional)

Prepare Firecracker Sauce: In medium bowl, whisk together lime juice, maple syrup, ketchup, olive oil, soy sauce, garlic, crushed red-pepper flakes, black pepper, lime rind, and salt. Makes about 1 C. Set aside. On one skewer, randomly arrange 2 pieces of cubed steak and one piece each of onion, yellow squash, zucchini, and red pepper. Repeat to make 11 more kabobs. Place kabobs in large baking dish. Pour 3/4 C. of Firecracker Sauce over kabobs in baking dish. Reserve 1/4 C. for brushing the kabobs as they cook. Let kabobs stand for 15 minutes. Heat grill to medium heat. Grill kabobs about 4 inches above heat source for 5 minutes, turning frequently. Brush kabobs with reserved Firecracker Sauce. Cook 5 to 7 minutes longer or until desired doneness is reached.
