Time 50m

Number Of Ingredients 7

1/2 cup balsamic vinegar
1/4 cup olive oil, plus more for grill
1 tablespoon chopped fresh rosemary
Salt and pepper
1 1/2 pounds top blade beef, cut into 1 1/2-inch pieces
8 ounces button mushrooms
2 red bell peppers, cut into 1 1/2-inch wedges

Steps:

Combine vinegar, oil, rosemary, and 1 teaspoon salt and 2 teaspoons pepper. Reserve and refrigerate about 1/4 cup of marinade. Transfer remaining marinade to a zip-top bag and add beef and toss to coat. Refrigerate 8 hours (or up to overnight).
Heat a grill or grill pan to medium-high. Clean and lightly oil hot grill. Thread some skewers with beef, others with mushrooms, and others with peppers. Season with salt and pepper. Grill mushroom and pepper skewers for 9 to 12 minutes and beef skewers for 12 to 15 minutes, turning all skewers frequently and brushing with reserved marinade.
