Sandwiches make such satisfying lunches during the summer. This one is a summer classic! It’s healthy, light, vegetarian and full of flavors that remind you of a hot summer day! Grilled zucchini placed between two slices of high-fiber, whole grain bread, smeared with a low-fat basil mayo spread, topped with red onion, tomato and fresh bocconcini cheese, crisped up to golden perfection and you have a spectacular culinary delight! Healthy, low in sodium and fat and simple to make!
