Grilled vegetable skewers are a simple and delicious way to enjoy a variety of veggies. Start by cutting your favorite vegetables into bite-sized pieces, such as bell peppers, zucchini, mushrooms, cherry tomatoes, and red onions. Thread the vegetables onto skewers, alternating the different types for a colorful presentation. Brush the skewers with olive oil and season with salt, pepper, and your favorite herbs or spices. Grill the skewers over medium heat for about 10-15 minutes, turning occasionally, until the vegetables are tender and slightly charred. Serve as a side dish or as a main course with a side of rice or quinoa.
