Don't forget, what is inexpensive for me might NOT be inexpensive for you (depending on season, location, availability etc). Some folks have inexpensive meats or eggs while other don't. Sometimes broccoli is a steal and then other times (like here in New England right now) the prices SPIKE due to weather issues in other states. So while some recipes are kind of "universally" frugal, others are more dependent on outside influences. Think about what your frugal INGREDIENTS are and work from that
Black beans ($1.69 for 2 lbs)---cook them until almost done.
Add:
Bag of southwest corn from Schwans ($7.50)
1/2 jar salsa (I like either the chipotle version from Tostidos or the either the roasted tomato or chipotle one from Frontega $1.50)
salt, pepper, cumin, oregano to taste
Serve with some tortillas, cheese, cilantro, lime...whatever I have in the fridge.
it makes me happy to read all the recopies here that use dried beans because that means people actually know how to prepare them. it never ceases to amaze me when I encounter someone (not an inexperienced cook) who doesn't know how to. the food bank that was located in the social services building I worked in had so many hungry people who would decline taking dried beans because they just didn't know how to prepare them that we finally made up a printed sheet that went into each bag with easy soaking/boiling instructions (we also had to do this to some extent with rice-there are those who REALY do not understand that it doesn't take a rice cooker to make rice).
