Idk wtf to do about food

I don’t know how we do this but the 2 of us can’t eat all of our food before it goes bad.

We eat everyday with the exception of lunch because we both eat lunch at work and our jobs provide us lunch.

We don’t even eat 50 dollars in groceries a week and I don’t know how we are doing that. I know we eat small amounts but that’s all we need to be full.

It’s just a pain in the ass that so much of our food goes bad before we can eat it.

We are in our 20s and still learning how to adult. What can I do? I tried buying less and less food during my shopping trips. It still expires before we get to it.

Edit: the things that go bad the fastest are bread and milk. Can you freeze those?
