05 - Place 2-3 tablespoons of the ricotta mixture at one end of each eggplant slice and roll up gently.
06 - Arrange rolls seam-side down in the baking dish.
07 - Spoon the remaining marinara sauce over the rollatini. Sprinkle with the remaining 1 cup mozzarella and breadcrumbs.
08 - Cover with foil and bake for 20 minutes.
09 - Remove foil and bake for another 10-15 minutes, until bubbly and golden.
10 - Let rest 5 minutes before garnishing with basil and serving.
