Preheat oven to 375 degrees.
On a half sheet pan, arrange eggplant in a single layer. Sprinkle with the salt and pepper and drizzle liberally with the olive oil on both sides to prevent sticking.
Bake for 7-8 minutes then carefully flip eggplant rounds and return to oven.
Bake an additional 7-8 minutes until both sides are golden and tender and most moisture has released. Set aside.
While eggplant slices are baking, prepare the Truffle Parmesan Breadcrumbs. In a small bowl, combine all ingredients with a small fork or spoon.
Raise oven temperature to 425 degrees. Add your flatbread to a sheet pan to assemble. Begin by adding 1/2 of the marinara to crust, distributing evenly. Next, arrange eggplant slices in a circular pattern all across crust, overlapping just slightly.
Add sliced mozzarella all across crust, finished with small dollops of remaining marinara. Sprinkle Truffle Parmesan Breadcrumbs all across.
Bake flatbread according to package directions, about 14-16 minutes total, rotating the pan 180 degrees midway through cooking.
Serve finished with more grated parmesan and fresh basil leaves. Slice then serve immediately. Enjoy!
