We actually use leaf and romaine lettuce as a wrap for a sandwich. Just take your favorite meat, my husband uses ham, I like chicken, put on some diced tomato, maybe avacado or some greek yogurt with a bit of hot sauce in it. Put it in the middle of the leaf and eat it sort of taco style. My son and I used some leftover Chinese food the other day. You will need to pick your biggest leaves and it can be a bit messy, but what a healthy way to eat a sandwich.
