Chipotle's flour tortillas for both its tacos and burritos are vegan, so you can easily make a vegan or vegetarian burrito to suit your taste buds.
Again opt for some white or brown rice for your base. Chipotle's rice is made with bay leaves, lime juice, and cilantro, making either rice a great fit along with lettuce, guacamole, salsa, and, of course, beans and fajita veggies.
Vegetarians again can add in cheese or sour cream.
