It's my understanding you can get really fancy with them!
... you can also dump a pile of meat in a bag full of applesauce and leave it in the fridge overnight and make something delicious. So, y'know. Plenty of space to play with

e: also finally got around to trying to make home fries in our air fryer, which, uh. Take potatoes, cut them into 8ths long ways, then half everything (basically cut them into 16ths), season to taste, fry at 400f for about 15-18 minutes. Turns out it's stupid easy. Seasoning this time was olive oil, paprika, black pepper, and curry powder. Was pretty okay! Definitely could have used salt (or something equivalent), but 2/3rds* of the people I was cooking for are supposed to be minimizing the stuff, so.
*among which is now me, which is... probably going to lead to a lot more cooking in the future. It is goddamn
impossible to find unsalted frozen or otherwise preprepared food, especially at a price point that isn't ridiculous.
