These Mediterranean chicken and vegetable kabobs are a fresh, colorful option for your next backyard cookout. Chunks of tender chicken breast marinate in a bright blend of lemon juice, olive oil, garlic, and rosemary before hitting the hot grill. Threaded alongside sweet red bell pepper, zucchini, and red onion, the skewers develop a beautiful charred edge. Fresh asparagus spears grill right alongside the kabobs for a complete meal. A final scatter of crumbled feta cheese adds a salty, creamy finish that ties the dish together.
