What do you think are the justice league member's favorite snacks/meals they like to cook/eat?
Dear anon, I am so glad you asked. Allow me to explain
J'onn - literally everyone is concerned. J'onn eats stuff that's not food just because he can. He will snack on drywall. He eats bugs off of leaves. The actual food he eats isn't much better - his diet consists almost entirely off of processed sugar. Obviously chocos/oreos, but also just the kind of things a seven year old would pack for lunch. Twinkies, sugary cereal, actual candy, donuts, popcorn, chips, etc. He tries, half-heartedly, to insist that Martians nutritional needs are different than humans, but there is literally no evidence to suggest that. Someone in the JL takes him out to eat/brings him food almost every day to make sure he doesn't die.
Wally - only marginally better than J'onn in that he won't eat chalk unprompted. We all know speedsters, they need a lot of food to keep up with their metabolism and energy, but Wally is especially ludicrous in the "will eat anything" category. He will put anything and everything in the fridge into a sandwich, which sounds like a fun thing to ask about, but eventually everyone realizes they just don't wanna know. Also a connoisseur of wild food combos ("icing in chili??" "Hey don't knock it til you try it")
Shayera - A little bit more normal but the bar is in hell so that doesn't mean much. She will try anything at least once, especially on a dare. She also just has an insane pallete for space food. Meals on thanagar were really just anything slightly edible thrown into a trough, so anything that's cooked is fine dining. Also sometimes things that aren't cooked. Raw chicken is one of her favorite snacks - She likes to chew on (and eventually eat) the bones
Bruce - now we're reaching slightly normal human foods, but that doesn't mean Bruce's diet is normal. Honestly, he's just autismcore with a splash of "do rich people really eat that?". His schedule is so fucked he rarely ever has time for an actual meal, so mostly he eats what he can when he can. I have fully adopted the fandom canon that he eats shredded cheese right out of the bag. When he does eat a real meal, it's part of a carefully crafted food schedule developed over decades. He essentially has 31 meals, one for every day - a good mix of recognizable foods and "some guy I traveled the Amazon with made this for me in 1986".
Diana - we have now reached the "can cook" section. One caveat for Diana though, she has no idea how kitchen appliances work. If the oven isn't made of stone she may set something on fire. She's used to the best Themyscira has to offer, lots of fresh fruits and vegetables and elaborate feasts. She can't really manage a feast in her apartment, but she knows a good few meals, she eats well. However, she's often too busy to make her own food, so it's like 60% take out.
Clark - this boy eats three square meals a day no matter WHAT. If you sleepover with Clark there will be pancakes and eggs on the table by the time you wake up. He's just a big country boy, his ma taught him well and he uses it. He cooks for himself pretty much every day, the only exception being occasionally going out for lunch during work or picking up a hot dog from a cart (he loves them, no one can understand why).
John - John is your uncle that got really into meal prep. He is religious about his food intake, he only eats the best and has every meal scheduled like a month in advance. He picked up a few recipes from his mom, but he really just picked up a passion for cooking well at some point just to challenge himself. He also eats really healthy, he's known to occasionally go on some weird keto diet that everyone makes fun of him for. He's the kind of person who eats overnight oats. He lectures Wally about his eating habits daily.
So. That was a ridiculous amount thought and effort for a simple headcanon question. This is what they inside of my brain looks like 24/7 thanks got asking <3
