Tell me you're at least looking for a job, I'll go ahead and give you the benefit of the doubt and assume you are, but at least tell me you're trying.
Be sure to mix it up with Ramen noodles. Do something like beef one day, then chicken the next, then shrimp the next. Buy a variety of all the types you like.
Some other really cheap foods I can think of are:
Banquet Pot Pies are very cheap, ranging below a dollar at all times. I personally don't like them, but my parents love them.
Also, instead of getting name brand foods try off-brand, like there off brand Fruit Loops.
Off the McDonals Dollar Menu you can get a McDouble and a value fry for two dollars, and a large water. Also, any time you go to a fast food place pick up plenty of ketchup and sauce packets. They come in handy do you don't have to buy ketchup bottles or sauce.
I think this has been a little bit helpful. :3
