These Mediterranean veggie skewers are packed with flavor and are perfect for a summer barbecue. The secret to these skewers is the combination of fresh vegetables and Mediterranean spices. The skewers are made with cherry tomatoes, bell peppers, red onions, zucchini, and mushrooms, which are marinated in a mixture of olive oil, lemon juice, garlic, and a blend of Mediterranean spices. Grill these skewers until the vegetables are tender and slightly charred. Serve them with some tzatziki sauce and pita bread for a complete meal.
