High-ish protein, low effort pre gym snacks?

Hey y'all,

I'm looking for some ideas on the above - high protein, low effort - pre gym snacks that isn't gonna break the bank. I've looked into a lot of protein bars and snacks and they're just ridiculously expensive for one package. Any homemade recipes would be greatly appreciated! Ideally those without adding protein powders but I understand that's a tall ask, but can throw in recipes that don't ask for half a bag of powder, lol.

TIA~
