Once eggplant is cool enough to handle, flip them over flesh side up. Using a spoon gently scoop out the the flesh leaving the skin intact on the sheet pan as much as possible. Transfer the flesh to a medium bowl.
To the bowl with the eggplant, add 1 1/2 cups of you tomato sauce and stir to combine. If it seems too dry and a little more sauce. Once well combine, taste and adjust the seasoning if needed.
Spoon the eggplant & sauce mixture back into each skin making sure to distribute evenly.
Take the cubed mozzarella and top each filled eggplant with about 2oz each. Making sure to gently push them down into the filling so they're don't fall out.
Combine the breadcrumbs, 1/2 cup of grated parmesan, and 2 tbsp. of olive oil into a small bowl. Sir well to make sure all the breadcrumbs are coated in oil. Spoon the mixture over the top of each eggplant until each one is nicely topped and all the mixture is used.
Place the eggplant back into the oven and bake for 20-30 minutes until the breadcrumbs are nicely browned.
Remove from oven, top with fresh basil and serve! I serve 1/2 per person. Serve additional grated parmesan on the side for anyone that's wants it! Enjoy!
