Slice your eggpants and put them in salted cold water for 5 minutes
Dry them with a paper and grill them to soften (no oil needed)
Spread a little of the tomato sauce and put the eggplants in a oven proof dish
Add the ham. I like to shred it first because its easier to serve this way.
Add the cheese.
And the Tomato sauce. Repeat until the tray is filled.
Top it off with tomato sauce and the grated cheese. Cover it with aluminum foil. Now oven for around 45 minutes at 365F or 180C. Enjoy!
