Preheat your oven to 400 degrees f. and line 2 large baking trays with parchment paper.
To prepare the eggplant, cut the stems off and discard them. Slice them lengthwise into 1/4-inch slices.
Lay the eggplant slices onto your prepared sheet pans and season with sea salt and pepper. Spritz with a teeny bit of oil.
Roast in your preheated oven for 16-18 minutes, flipping halfway.
Meanwhile, in a medium bowl, combine the ricotta cheese with 1/2 of the mozzarella, and all of your seasonings.
Spread about 1/4 of the marinara sauce into the bottom of a medium baking dish.
Once the eggplant is done roasting, remove it from the oven and allow it to cool for a bit, just until ready to handle.
Add about one heaping spoonful of your cheese mixture to one end of your eggplant slice, roll it up, then place it into the prepared baking dish as shown.
Repeat with the remaining eggplant slices and cheese filling.
Top the rolls with the remaining marinara sauce then sprinkle with the remaining mozzarella.
Bake for 30 to 40 minutes until the cheese is melted and the sauce is bubbling.
Garnish with freshly chopped herbs, and red pepper flakes, then enjoy!
