This is a nice change from using bread or similar products for sandwiches. The center rib of Romaine Lettuce leaves tend to snap when you try to roll them up, so use Green or Red Lettuce leaves, if you can.

large Green or Red Lettuce leaves
any fillings you can think of
any sauces, dips, condiments you have on hand

1. Just put any kind of filling: tuna salad, egg salad, tofu salad, rice, peanut butter, leftover stews, beans, etc., into the middle of a large lettuce leaf. Roll it up and eat.

Just great!
