If you're looking for a portable and easy-to-make veggie sandwich, try a roasted vegetable wrap. Start by roasting your favorite vegetables, such as bell peppers, zucchini, and onions, in the oven until they are tender and slightly caramelized. Spread some hummus or tahini sauce on a whole wheat wrap or tortilla. Layer on the roasted vegetables and add some fresh spinach or arugula for a pop of green. Roll up the wrap tightly and slice it into bite-sized pieces. This sandwich is perfect for a quick lunch on the go or a light dinner option.
