All you need for your basic burritos are 32 burrito-sized flour tortillas, two dozen eggs, four cans of black beans, a jar of salsa, some saran wrap, and some green onions (optional) and shredded cheese (optional).

That's all you need to make thirty two delicious breakfast burritos. Let's figure up the total cost.

• Three dozen tortillas - $8.85 ($2.95 per dozen)
• Two dozen eggs - $4.40 ($2.20 per dozen)
• Four cans of black beans - $6.00 ($1.50 per can)
• Saran wrap - $3.95
• Jar of salsa - $2.95

Total cost - $26.15 ($0.72 per burrito)

• You can easily save $4 on the black beans by buying a bag of dried black beans and boiling them yourself, but it would add some significant time to the cooking process.

1. If you're adding any vegetables (see below, Some Optional Ideas), put these in a medium pot and cook them over medium high heat for a few minutes before doing anything else. This caramelizes onions and peppers, for example.
2. Open up all of the cans of beans and drain off the sauce. I put the beans in a strainer and run water over the top because I do not like the sauce that beans are packed in.
3. Crack all of the eggs into a bowl and beat them with a fork until they're roughly consistent. Pour this egg mixture into a medium pot (with the vegetables, if you're using them) and begin cooking the eggs over medium heat. Stir them constantly, scraping any cooking eggs off of the bottom of the pan. As soon as the eggs just start to cook, add all of the beans to the pot.
4. Keep cooking the egg/bean/vegetable mix, stirring continuously and scraping eggs off the bottom and side of the pan, until the eggs are thoroughly cooked. Remove from heat.
5. Take out a single tortilla and put a large spoonful of egg mixture onto the tortilla (about two heaping tablespoons). Put a tablespoon or so of salsa on top, along with anything extra (see below, Some Optional Ideas). You'll want to put the eggs and salsa in the middle of the burrito, near the bottom.
6. Folding these up is easy. First, fold over the sides of the burrito, mostly covering the ingredients then just roll this up from the bottom tightly.
7. Burrito's done! Just wrap it in Saran Wrap and move onto the next one.

The entire process, by myself with no help, took about an hour. The burritos themselves cost about seventy cents a piece, though I could have done things to make them cheaper (like using dried beans and cooking them myself and using cheaper ingredients).

Here are a few good optional things that can jazz these up some more.

• Spicing the eggs: While cooking the egg mixture, add one or more of these: tarragon, chili powder, garlic powder, black pepper, red pepper.

• Green onions or peppers: Chop up some green onions or peppers and cook them in the pan for a few minutes before you add the eggs. Tip: if you do green onions, use scissors to cut them up directly over the pot instead of using a knife.

• Cheese: Put a bit of grated cheddar cheese on top of the eggs and salsa just before you close up the burritos.

Reheating these burritos is quite easy - and they don't have to be dry, either.

• Simply take a burrito out of the freezer, take off the saran wrap, and wrap the burrito in a paper towel. Put it in the microwave on defrost for two minutes, then cook on high for a minute and a half or so. This will produce a warm, moist burrito. You may need to play with the exact times a bit depending on your elevation, your microwave, and the size of the burrito you made.
• Let it cool for a minute or two in the microwave, then you can easily

carry the burrito with you in the paper towel. The paper towel will help prevent any leakage and can provide a napkin when you're finished.
