Reddit reviews Mission Foods Heat Pressed Flour Tortilla, 13 inch - 12 per pack -- 12 packs per case.

I know you're not serious, but people have looked at me dead in the face and asked these questions.. so here goes:

When Catering Your own Burritos

• How casual is the attire for your event? Burritos can be messy, especially if people make their own or proper utensils aren't supplied.
  
  
• In addition to chafing dishes, you'll need serving utensils, plates, foil, and eating utensils.
  
  
• Will you be indoors or outside? It's easier to keep food at acceptable temperatures inside (don't make food poisoning the reason guests remember your wedding) unless you have access to power and ice while outside.
  
  
• How many guests will you be serving? How prepared do you want to be for surprise guests? What will you do with any significant amount of leftover food? Will you need to accommodate any food allergies?
  
  
• Do you want a make-your-own burrito bar or will someone be prepping them for guests? Again, your guests will likely make a mess, unless you invite a lot of Chipotle employees. Your guests will also serve themselves at a snail's pace. A cafeteria style buffet line is best, but then you need willing volunteers or you'll need to pay servers.
  
  
• Will you be using basic [aluminum pans with holders](http://www.partycity.com/product/chafing+dishes+aluminum+pans.do#Chafing Pans & Lids) and sterno or will you purchase/rent fancy looking equipment?
  
  
• Will size tortillas will you use? Here are some 13" and here are some 10".
  
  
• How will you steam the tortillas and/or keep them warm as well as prevent them from tearing and sticking? Most non-industrial steamers heat one 10-inch tortilla at a time. A professional steamer runs upwards of $400, depending on capabilities. Unless you have an exorbitant budget (which you don't if you're DIYing catering), can find a good rental place, or want to open a restaurant after your honeymoon an industrial steamer probably isn't worth it.
  
  
  
• What toppings will you provide? Generally offered are: seasoned rice, black or refried beans, grilled peppers and onions, corn salsa, picante, regular salsas, flavored and regular sour cream, olives, jalapenos, onion, lettuce, cilantro, tomatoes, and shredded cheese. Guacamole and melted white cheese (queso!) are also popular.
  
  
• You need about a tablespoon (poker chip) to two tablespoons (golf ball) of sour cream, depending on the guest and the other toppings (0.5oz to 1oz).
  
  
• There are thousands of burrito recipes online and a ton of recipe multipliers.
  
  
• You need about 4oz of meat per burrito, 6oz if the guest doesn't want any rice/beans. You need about 2-3oz each of rice and beans. The other toppings are according to preference and how they'll fit in the tortilla.
  
  
• I would consider doing taco bowls instead of burritos.
