Veg-forward sandwiches can no longer be an afterthought—they are a menu must-have. While fresh, seasonal vegetables are inherently tasty, grilling incorporates another layer of flavor. The Grilled Veggie Wrap from Metro Diner combines portobello mushrooms, zucchini, yellow squash, sweet potatoes and red and green bell peppers in a flour tortilla. The veggie filling not only gives customers a more sustainable, plant-based option, but using a tortilla as the carrier also lightens up the sandwich and makes it even more portable.
