Bought a whole green cabbage at the grocery store in a fit of pique and now I need suggestions of what to do with it

Favorite cabbage recipes anyone?? I’m autistic so the grocery store is like the most dangerous place for me and I just like, decided I needed this cabbage, “because it will store long”, and then completely forgot to like, google what you do with cabbage.

I was raised Italian American as hell and was never forced to eat my vegetables and I realized there’s a chance I’ve literally never even eaten cabbage.

Anyway, please help.
