[QUESTION] what's good recipes or ideas for someone who is extremely poor and rarely can't buy much but potatoes

Watching mythical kitchen about hash browns and wondering if anybody have any ideas on how to make potatoes into other things that are extremely cheap. I usually have only potatoes and margarine at last 2 weeks before I get food stamps because it isn't enough to cover basic food things.

Does anybody know any good ideas or recipes or something that does not require a lot of other one time ingredients? That's really cheap on quantities, like spices, where it can last a while with it being really inexpensive.

Things I have is absolutely basic cooking skills and cooking appliances. Microwave oven and stove. I don't have much of anything because and can't afford anything

Anybody have any ideas or recipes or thoughts?
