Gratin Potatoes Eggplant

A nice friend and neighbor brought me a couple of beautiful eggplants. I sliced them thin over the top of my scalloped potatoes, sprinkled chili oil over that, and layered on some cheese.  Next I nuked them in an air fryer until the top was crunchy and brown. 

Eggplant is related to the potato, so maybe that wasn't awfully different, but it was the first time I made it that way.   Usually I slice the eggplant thick, dip the slices in beaten eggs and then in romano cheese and fry them up in butter until soft.
