Burritos by the Box costs $7.80 per person in my area and includes chips and salsa/guacamole (It's one bag of chips and side of sour cream for every two burritos ordered). The burritos are made with: cilantro-lime rice, vegetarian black beans, mild fresh tomato salsa, and cheese plus your choice of chicken, steak, carnitas, barbacoa, or vegetarian options
You can download the order form for your local Chipotle from their website.
