Preheat a charcoal grill to high or an oven broiler to 500 degrees. If wooden skewers are used, soak them in cold water until ready to use. Cut the beef into 3 cm cubes. There should be 24 cubes. Peel and cut the onions into 24 3 cm cubes. Reserve the remaining onion for another use. Set the cubes aside until ready to cook. Cut away and discard the pepper cores and seeds. Cut the peppers into 24 equal-size pieces and set aside until ready to cook. Combine the meat and remaining ingredients in a mixing bowl. Blend well and marinate for 15 minutes. Drain the meat and arrange equal portions of meat, onions and peppers on skewers. Reserve the marinade for basting. If the brochettes are to be cooked under the broiler, arrange them on a rack about 10 cm from the source of heat, leaving the door slightly ajar. Cook for about four minutes for rare, basting with reserved marinade and turning often. If the brochettes are to be cooked on a grill, place them on the grill and cook for 4 minutes for rare, basting often with the reserved marinade while turning UPL by Dr. Jim Culveyhouse 73330,2525
