So, it seems like the biggest issue here is picking food that lasts up to 5 days. Any tips?

I love making these salmon cakes https://aggieskitchen.com/old-bay-salmon-cakes/

but salmon should only be fringed for 1-2 days. I heard usually stew and chicken meals last a good ‘while. I have the will to do this but I’m at a lost for finding yummy long lasting recipes I can cook in bulk.
