How to eat healthy and cheap.

Hey guys. As you can see, i'm writing this on english language. I decided to write on english sometimes, or everytime...
Anyway, so a lot of people are telling me that they can't eat healthy, because they are in college or something like this and they don't have so much money for healthy food. Most of people think that the good food is expensive food. But this is very wrong! Now i'm going to tell you some kind of food that is healthy and cheap.
Eggs:
6 grams of proteine in each egg, and they are very cheap and similar for bodybuilding eating.
Rice:
Rich carb food and very cheap.
Potatoes:
Also rich carb food and cheap
Peanut butter:
This one has lot of calories, proteine and healthy fat. It gives a lot of energy and it's cheap.
Oats:
Just perfect food. Very cheap, gives energy and satiates.
Meat:
Yeah, the meat... It's not so cheap, but it's neccessary. And i think that if you eat 300 or 500 grams meat a day it won't be so big problem for your budget.
