Grilling the meat and vegetables at the same time gets dinner on the table quickly. For more vegetable options, try grilling asparagus, portobello mushroom caps, and corn on the cob, too.
4 servings (serving size: 3 ounces steak and 1 cup vegetable mixture)
Prepare grill or broiler.
Sprinkle steak with 1/4 teaspoon salt and 1/4 teaspoon black pepper.
Combine 1/2 teaspoon of salt, 1/4 teaspoon of black pepper, vinegar, and next 5 ingredients (through garlic) in a large zip-top plastic bag. Seal and shake to coat.
Place steak on grill rack or broiler pan coated with cooking spray; cook 4 minutes on each side or until desired degree of doneness. Let stand 5 minutes; cut steak into 1/4-inch slices. Place zucchini and squash on grill rack or broiler pan coated with cooking spray; cook for 4 minutes on each side or until tender. Place bell peppers and onions on grill rack or broiler pan; cook 2 minutes or just until tender.
Coarsely chop vegetables; place in a bowl. Add pesto; stir gently. Garnish with oregano, if desired.
