Heat grill. In small bowl, combine margarine, cilantro, cumin, garlic salt and hot pepper sauce; mix well. Alternately thread corn, peppers and steak onto four 12 to 14-inch metal skewers.
When ready to grill, place kabobs on gas grill over medium heat or on charcoal grill 4 to 6 inches from medium coals. Cook 8 to 12 minutes or until corn is tender and beef is of desired doneness, turning once and brushing frequently with margarine mixture.
