OK, I have to say again, Don't forget the beans!!!!!! They are soooooo cheap. Just eat them a few times a week and it makes SUCH a difference. We have bean tacos for lunch most days. The recipe is on
www.helpmybudget.com under "Eat on 35 cents per person" I know the book "not just beans" was mentioned, which is great b/c you need to eat something cheap besides beans, but I don't think you can get cheaper than beans. Plus, they are so so so so healthy. I think they are super tastey also, but that's me. Of course, I use the recipe mentioned above. If someone had just told me in the past "eat dried beans" I would not have ANY idea what to do to a dried bean to make it edible.
Meatless meals really help the budget. I also make tofu tacos (and i don't normally like tofu). I saute onions and mushrooms with garlic salt and then add hard tofu chunks towards the end. I fry corn tortillas in just a little oil to soften them and there you go ! Just add a side of beans!
