What I think some of the hermits would bring to a potluck
Grian- Bread (He made it himself, but doesn't say it at first in case people think it's bad.)
Mumbo- He brought basically every vegetable he grows and made a veggie platter.
Scar- He decided to bring out his old cotton candy machine. Totally not because he burnt his pie...
Skizz, Impulse, Tango, Zed- They all teamed up to try and smoke a turkey. Tango had attempted to do it alone, but the other 3 put a stop to that. That did lead to Zed trying to use anything but a smoker, but it still turned out ok.
Joel- He couldn't be bothered to cook anything, so he just bought some sprinkled sugar cookies. He did cook once, but that was just to prove to Gem that he can. He regrets that now, because people will not shut up about it.
Etho- He brought his famous punch, cups, and a ladle. He's the only one that serves the punch.
Gem- She brought alcohol to try and spike Etho's punch bowl. She's tried every potluck, yet failed every time.
That's all I can think of right now.
