I vote for doing some cheese and cauliflower style pies, as they freeze well.

I’m not experienced with making pies and the online recipes look annoying. But I’d probably steam the veg, make a roux cheese sauce with garlic and onion powder, mix, then either use a pie maker or do pastie shapes with premade pastry sheets. It’s uh… a hand pie. Yeah.

Wait shit it is

Edit: You can also make a few different meals with it, it doesn’t have to be just one
