I have an air fryer. I thought it would absolutely revolutionize my rv cooking experience. It didn't. What did revolutionize it was my instant pot, which I use almost every day, sometimes twice a day. It is the best thing since sliced bread. I can make authentic tasting baked ziti with five minutes prep time, and 5 minutes cook time, make delicious chicken and rice recipes, hearty stews, with almost no effort at all. I love it!!
Anyway... what I found is that the air fryer is often times my go to for lunches. I make fish sticks, tater tots, pierogies, etc in it. I have made tuna patties in them instead of frying them and they turned out perfectly. Also, fried raviolis are a great easy and tasty dinner, just egg, breadcrumb and and airfry and serve with a veggie and some marinara to dip. The recipe is at the bottom of the pinterest board.
I have the bigger model with 3 racks, I have to rotate the racks and flip the items halfway through so the ones on the top rack don't get overcooked. Sometimes I wished I had gotten the one with the basket so I could just shake it around.
Anyway, here is my air fryer pinterest board which has some good ideas on it, and below is a link to a potato slicer from amazon to make air fryer french fries, which is where this gadget really shines. Hope this helps.
