You can either grill your eggplant slices on the barbecue or in a pan or roast them like I did.
Sprinkle your eggplant with salt and let them sit for 15 minutes. Then take a paper towel and blot them to remove excess moisture. This step prevents sogginess and that bitter taste they typically have.
Preheat oven to 420 F. Line a baking sheet with parchment paper.
Transfer the slices to your baking tray so that none are overlapping and spray them with olive oil. Season them with salt and pepper to taste. Bake for 10 minutes. Remove from oven, flip them over and spray the other side with olive oil. Season to taste. Pop back in the oven for 7 minutes.
In a small bowl, mix the breadcrumbs, pecorino cheese, Italian seasoning and oil until combined.
Reduce oven heat to 375 F.
When stacking, first drizzle with the tomato sauce, then the breadcrumbs and lastly the mozzarella. Repeat so that there are 3 levels. Additional tip is to utilize the same size eggplant “coins” in each stack. Assemble and bake for 12 minutes or until heated through and cheese is melted.
