As a student I found myself out of funds quite often and Taco Bell helped fill my tummy while I was waiting for my account to fill up again. If I remember correctly the cheapest on the menu was the refried bean burito til $ 0.59 elle 0.69. This was a simple meal consisting of a tortilla, refried beans and salsa.
Sometimes I get nostalgic and I get a hankering for something from my student days tortillas, refried beans and salsa, these days I add a little extra but not much.
I called these vegetarian, but i think these are vegan, since no animal products were used in the making of them.
For these simple tacos you will need
Refried beans, for recipe look HERE
Pico de gallo, for recipe look HERE
Guacamole, for recipe look HERE
Sliced red onions
Simple and clean flavors
If you want you can probably buy everything ready made to make it easier and less time consuming, but if you make it you know what is in it and fresh tasting.
There is no right or wrong to what you put in tortillas, eat them with what you want and enjoy.
