These grilled vegetable skewers are a delicious and healthy way to enjoy a variety of veggies. The secret to these skewers is the marinade, which adds a burst of flavor to the vegetables. The marinade is made with olive oil, garlic, lemon juice, and a blend of herbs and spices. The vegetables are then threaded onto skewers and grilled until tender and slightly charred. Serve these skewers as a side dish or as a main course with some grilled tofu or tempeh.
