I'm going to piggyback on this, as my wife and I were just talking about making Fridays "Pizza Night" at our house. We love cooking together, and we've got a long-running-but-stale love of making sourdough pizza from scratch and doing it all up with the kids. It's intense, but scales reasonably as long as you get a head-count a few days out. We're so looking forward to sitting down with friends around our table again.
It started as a thing around BBQ as I have a small indoor infrared grill (all my friends have small places too).
Will also do other stuff like Mexican chili, bring your own steak and grill it etc. People bring drinks and snacks or dishes.
What inspired me.. My friend used to do it a few years back and somehow I realized it let's me become a social hub, have people invite their friends so I keep in touch with and make new friends.
