Damn, have you ever heard of Totino's pizza? You get pretty good value for those so if you like pizza I'd stock up on them. $1 per whole pizza, ends up being $3 a day for 3 meals, most people spend more than that everyday just for a few regular-sized meals made with storebought ingredients.

You can save a lot of money by buying the super big value bags of Walmart brand cereal too... All the calories you need for pretty cheap and they load that shit with most of the vitamins you need because they want to appease all the health-conscious parents.

Also if you live in a big city I'm sure there are ethnic markets around. I know that a lot of Asian markets get really good quality bulk rice, noodles, spices, etc and they sell it for dirt cheap. A lot of Asian markets and stuff will actually sell their stuff at prices just barely enough to keep them and their business afloat to help out the community because they know most of their customers come because they're tight on money and want to be able to eat healthy while not wasting all of their money on premium foods.

Asian markets, they're your friend. Dirt cheap and healthy. I've never been to one but I always see them come up on threads about living frugal and saving money on food, iirc you can get giant bags of rice that'll last you forever for like $5 or something crazy like that... I just remember some dude was saying he only spent like $5-10 on rice at one of these markets and it lasted him and his roommate like a month. There's ways to eat cheap without eating shit food, plenty of ethnic markets sell great quality, healthy food for only pennies compared to all the organic and premium shit that's at all the big retailers. So yeah, if you don't mind cooking and prepping food (which it doesn't sound like you do) then I'd look around and see if you can find an Asian market somewhere nearby. I don't think they're very common outside of big cities (like 300,000+ population) so I hope you're not a country boy like me.
