I love burritos , It is wrapped into a closed-ended cylinder, in contrast to a taco
I love burritos, too! But I don't know much about them. What kind of ingredients are normally in a burrito?
In the US fillings may include a combination of ingredients such as Mexican-style rice or plain rice, boiled beans or refried beans, lettuce, salsa, meat, guacamole, cheese, sour cream 
Do you know what guacamole is made from?
Yeah its normally avadoes as the base and lime and onion. Burrito sizes vary greatly though
That sounds really good. I guess I thought all burritos were the same size. Can you tell me more about how they vary?
Well The word "burrito" means "little donkey". So maybe the call them burritos is because they are small and carry stuff
I never thought of that before. It makes sense, though. Can you tell me anything else about burritos?
Well before the development of the modern burrito, the Mesoamerican peoples of Mexico used corn tortillas to wrap foods
Neat. Are burritos the only foods that use tortillas?
