Grilled vegetable skewers are a delicious and healthy way to enjoy a variety of veggies. You can use a combination of colorful bell peppers, zucchini, mushrooms, cherry tomatoes, and red onions. Simply marinate the veggies in a mixture of olive oil, garlic, lemon juice, and your favorite herbs and spices. Thread the veggies onto skewers and grill them until they are tender and slightly charred. Serve them as a side dish or as a main course with some grilled tofu or halloumi cheese.
