Doesn't have to be ridiculously expensive to eat well. I hit up the local farmer's markets (and ethnic markets...Indian/Asian/Hispanic markets often have produce and bulk spices at ridiculously cheap prices compared to mainstream grocery stores) and try to make a big batch of food every few days to munch off of, since my finances are now much tighter. Got some cheap chicken cuts, pierced them, tossed them in a bag with some Italian dressing, then pan-fried them. Made a box of chicken-flavored rice/vermicelli mix from ALDI's, and tossed up some green peas and mushrooms with a little butter and seasoned salt. Total price of everything was maybe $8. Made enough to get three full meals out of. That's pretty price-efficient and way better than just ramen.
Who said anything about just ramen

Though ramen's part of it. The noodles make an alright addition to several other things, and the seasoning's actually kinda' delicious when added to rice or potatoes. Y'just don't use a full pack of the stuff (in anything, including the ramen. That's some bloody strong junk.).
I tend to average about a buck fifty/two bucks per meal unless I'm particular desperate. Base of some sort of grain (rice, noodles) or potatoes, then additional seasonings and occasionally meat. And usually some cheese, heh. Every once in a while I'll get fancy, but you get inventive when you're low on funds so it still trends toward pretty inexpensive. I do seem to drive family members a little crazy when I go shopping with them, though, heh.
Do need to get around to scoping out the town I'm in now (for another week or two, possibly longer at some later point) for various deals, but... that comes later.
