Well you seem to be skipping over the fresh cilantro, herbs and spices, marinating time, and expert preparation found in a Chipotle. Do you understand what it takes to build and maintain a respectable and functional spice rack?

Not to mention the spoilage that goes on. The rice and beans can keep long-term, but you'll need to do logistics on chicken, tortillas etc to keep fresh ones in the pipeline without wasting any, which you can't afford either.

Look, I've had food boxes before. The food box is an amazing wondrous bit of charity where you can get a ton of free food just for asking. There's cereal, I've gotten big hunks of frozen meat, dry beans and rice, I've gotten bits of candy and such, lots of staples, powdered milk, canned chickpeas and spinach and you-name-it.

However the food boxes only go so far. They won't cook the meals for you. They won't give you the utensils, pots and pans. You don't get any fats, oils, herbs, spices, or seasonings. they won't tell you which ingredients combine in a flavorful way. You don't get any recipes that use these ingredients and don't call for something you don't have.

Now you boil some water, throw in some beans and rice plain, and cook until soft. Go ahead, throw in some string beans for vitamins, and some kind of protein. Spoil yourself! Then try to choke that down in the absence of salt, butter, or anything that might impart flavor. How long until you're going to just kill yourself?
