Found myself thinking about this bunch and decided I'd share some song claims. I have playlists for each of them (though Mimosa's is a bit empty), so I picked some of the songs that seemed most relevant to each. Plus, I figured I could use the doodles to do some minor design adjustments.
(I do also have Pinterest boards for them, but they're sections in a story board that I don't currently feel like making public, and while they aren't directly based off other characters, these four were all originally Neopets fan characters. Specifically, Apollo was a faerie grundo, Mimosa a desert xweetok, Bo a pirate kacheek, and Dezzy a mutant korbat.)
I couldn't for the life of me settle on something to draw for this (and I wasn't really happy with anything I tried), so instead you're getting some written stuff. Specifically, the prompt reminded me of two different story scenarios, so while I'm not going to be overly formal about it, I'm gonna talk about them under the cut.

Out of HayWire's main four, Sage is the team cook (and who I had initially wanted to draw for this prompt). It's something they picked up while traveling, and it just ended up getting more usage after moving in with the rest of the team. Considering none of the others are nearly as competent in the kitchen, everyone appreciates having someone willing to deal with food.
(As for the others: Envy can follow a recipe and knows a few simple ones but can't improvise to save her life, Volt was definitely surviving on microwave meals and the occasional restaurant visit when he lived alone, and Vesper is just used to others doing the cooking.)
Their first morning after moving in with the team (which had been just Envy and Volt up to that point), Sage decides to make breakfast but soon realizes that Volt doesn't have much more than cereal and some granola bars, so Sage picks up some extra stuff (and then more stuff as he gets ideas) and returns to start cooking.
This all happens before the others wake up. Due to worldbuilding-related reasons, Sage just generally doesn't need as much sleep as most others do, so when Envy wakes up and finds out just how long they've been up and around, she's reasonably concerned.
(Envy, however, is also the team glutton, so a well-made breakfast is more than enough to distract her, and Sage not being completely exhausted later in the day helps confirm that it's not a problem.)

The other notable story that has a definite team cook is Neon Lights. Bo acts as the cook aboard the ship the main cast travels on, the Scabbard (despite also being the quartermaster). It's a far more reasonable job when it's just the crew onboard, but a good portion of the story involves others traveling with them, so making sure there's enough for everyone gets a bit difficult.
Everyone tends to eat together on the main deck, so Bo can at least make adjustments to how much he makes based on who always has leftovers and who's never full.
One thing along those lines he notices is that Dezzy (the youngest of the main group, who the Scabbard's crew has essentially adopted) always ends up asking for more, and Apollo (one of the non-crew members traveling with them) always offers her his food. Bo's pretty perceptive, though, and he notices pretty quickly Apollo's doing this mostly to be nice and isn't actually getting a full meal.
Bo doesn't want to bring too much attention to it, since he doesn't want Dezzy to feel guilty about it and doesn't really know if Apollo's aware he's even doing it, so instead he just... makes sure he and Apollo are chatting while he makes meals and gets Apollo to taste test things.
Bo could definitely do it himself, but he plays it off as wanting a second opinion, and after a while it's just understood that Apollo's the kitchen assistant now.
(Bo confronts Apollo about it eventually, it's just tangled up in the other things he's dealing with, so Bo's willing leave it be while Apollo sorts some of the more obvious stuff out.)
