Grilled vegetable skewers are a delicious and healthy option for a veggie sizzler. You can use a variety of vegetables like bell peppers, zucchini, mushrooms, and cherry tomatoes. Marinate the vegetables in a flavorful mix of olive oil, garlic, herbs, and spices. Thread the vegetables onto skewers and grill them until they are tender and slightly charred. Serve the skewers with a tangy dipping sauce for a tasty and innovative veggie sizzler.
