Finally had what I'll call my first serious airfryer success!
For background, I ended up getting the Breville Air linked above (goes on sale for $329 from time to time). Note that this is a countertop
oven, not just a fancy toaster oven. It is also the largest countertop airfryer that I am aware of. Anyway, I've been working on my quesadilla game using this workflow:

It took me a good half a dozen cooks before I mastered the technique, because it's easy to over-cook or under-cook & not get that excellent crispy exterior on the tortillas. But once I got it figured out, I decided to try to figure out how to do meal prep using them. Microwaving them just made them soft & kinda soggy, and using my toaster oven didn't do the trick either. However, airfrying made them come out not only perfect, but better than perfect! They ended up puffing out really nicely, just like frozen pizza bites do!
I still have some more experimenting to do, as I've only air-fried these from the fridge (going to do freezer next to see how it affects cooking time & crispiness), but I've had excellent results sticking them on the rack in the cold airfryer oven & doing 6 minutes @ 400F in air-fry mode. Below is a picture of a shredded chicken salad quesadilla (plain pulled chicken, mayo, mustard, paprika, garlic powder, salt) with shredded mozzarella mixed in, pan-fried, cut into triangles, put in the fridge, and then air-fried a couple days later. The texture even got a bit more flaky, kind of like pie crust!
