Non-vegetarians can choose from egg, chicken, ham, turkey, fish or mutton. Stick to fresh, unprocessed meats, rather than processed ones.
Vegetarians can opt for hummus, nut butters, paneer or tofu.
4. Add some cheese.
Just because the sandwich is healthy, doesn’t mean it has to be boring! Add a slice of cheese if you like, preferably a fresh variety and not a packaged one. Cheese is fattening but it’s also rich in calcium, proteins, zinc, phosphorous and Vitamins A and B.
