Ingredients
1/4
cup garlic-flavored or regular olive oil
1/4
cup balsamic vinegar
1
teaspoon chopped fresh rosemary leaves
1
teaspoon salt
1
teaspoon freshly ground pepper
1
lb beef sirloin steak (1 inch thick), cut into 1 1/2-inch pieces
1
package (8 oz) whole fresh baby portabella mushrooms
16
mini sweet bell peppers, any color (about 3 inches long; from 8-oz bag)
5
green onions, cut into 3-inch pieces
2
cups cherry tomatoes
Preparation
In small bowl, mix oil, vinegar, rosemary, salt and pepper with whisk; set aside.
In resealable food-storage plastic bag, place beef, mushrooms, bell peppers and onions. Pour marinade over beef and vegetables. Seal bag; turn several times to coat. Refrigerate, turning occasionally, at least 3 hours but no longer than 8 hours to marinate.
Heat gas or charcoal grill. Remove beef and vegetables from marinade; reserve marinade. On each of 8 (10- to 12-inch metal skewers) alternately thread beef, mushrooms, bell peppers, onions and tomatoes. Brush with reserved marinade.
Place kabobs on grill over medium heat. Cover grill; cook 6 to 8 minutes, turning 2 or 3 times, or until beef is of desired doneness.
