Preheat the oven to 425°F. Cover two baking sheets with parchment paper and set aside.
In a shallow bowl, beat the eggs until cohesive. Add a splash of water and beat again to mix. Set aside. In another shallow bowl, mix the Panko bread crumbs, Italian herbs, freshly grated parmesan, and kosher salt. Create somewhat of an assembly line with your sliced eggplant, egg wash, crumb mixture, and parchment-covered baking sheets.
One at a time, dip your eggplant rounds into the egg wash, dredge them into the crumb mixture, then place them onto a baking sheet. Repeat this step for each eggplant round. When done, bake the eggplant rounds for 20-25 minutes or until golden crisp, flipping them over halfway through. When done, remove them from the oven and set them aside.
Evenly coat the bottom of a cast iron skillet or baking dish with a thin layer of tomato sauce. Then, lay down your first layer of eggplant rounds. Add a heaping TBSP of tomato sauce over each round, and then sprinkle some shredded cheese over top. Then place down your second layer of eggplant rounds. I like to keep the eggplant rounds evenly stacked so that's it's easier to scoop up for a serving when it's done. Again, add a heaping TBSP of tomato sauce over each round, and top them with cheese. Repeat these steps until you're out of rounds. Smother the topmost rounds with tomato sauce and cheese.
Cover with tin foil and set in the oven to bake for 10 minutes. After 10 minutes, remove the foil and bake for another five minutes, or until the cheese starts to bubble and turns lightly golden. When done, remove from the oven and set aside to cool for about five minutes.
Garnish with fresh basil and serve with your favorite pasta, fluffy rice, on a bun, or on it's own.
