Spaghetti or meatless Spaghetti. A jar of sauce and noodles.

Potatoes, make em anyway, they are usually cheap and take little ingredients. Mashed, roasted, fried…

Avoid prepared foods though, they cost more than doing the work yourself.

Cradle of filth

In this moment

Kitty (not so much anymore, was old band)

I use it, and seems to work for me. Used to have pain from cold stuff amd now I don’t even notice it.

Also home computer manuals and some hifi and lab equipment manuals which came with full schematics and measurement and calibration procedures. They essentially gave all users the maintenance manual and not just the dumb user one.

I wish this was more of a thing. Right to repair!
