Sirius used to be the one who cooked. Not that he was a lot better, but he knew more spells for it.

Remus works hard on his side, trying his best to keep up with the conveyor belt. He still ends up sweeping another pile into his apron. "No, I suppose not. I'd been in schooling or fighting a war until about a year ago, so I should possibly give myself a bit more leeway."

There were still some meetings of the Order. Molly Weasley loved cooking and would usually provide something for said meetings. She tried to make him take leftovers home with him, but he wasn't the one who had kids at home.
