Now, I don't know your situation but if you need food and you are in a financial bind not just looking for stuff that doesn't expire. Check out your local food bank/pantry. There's no shame in that.

Personally I do a lot of canning and foraging for things. So food storage is pretty important. I don't buy a lot of groceries. There are a lot of options for long lasting food, but too many to share.

I definitely would look up homesteading and some recipes from that.
