Can you eat taco-style food without a tortilla? A tortilla is thin, flat bread. Yes, you can use a lettuce leaf. The leaf can hold meat, beans, and cheese. It is green, fresh, and easy to eat. (theicn.org)
Here is an easy lunch example. Put warm beans on a large lettuce leaf. Add tomato and a little cheese. Fold the leaf with your hands. Then take a bite. It is like a taco, but different. No tortilla is needed. Try it at home!
