I found out that Air Fryers are basically specialized easier to clean (small) convection ovens. When we moved we didn't bring our heavily used toaster oven and I am missing some of the things I used to make. I am considering getting another toaster oven for a number of reasons and I will want the convection features if I do.
Chicken parts like thighs and legs worked particularly well. Fast and crispy.
One of my friends has medical conditions that limit her foods. After her gall bladder removal she just couldn't tolerate fats and her beloved french fries were taken away from her as well -- Air Fryer to the rescue!
