Preheat oven to 350 degrees.
Cut off the tops/stems of the eggplants. Slice them lengthwise. Using a spoon, scrape out the majority of the insides to leave about 1/4-1/2 inch shell. Set the shells aside.
Place all the insides of the eggplant into a food processor and pulse until finely chopped. Transfer this eggplant to a large bowl and mix together with the ground turkey, bread crumbs, parsley, parmesan, garlic and salt and pepper.
Set filling aside and heat 1-2 T. of olive oil and 2 cloves of minced garlic in a large skillet. Lightly sauté both sides of the large eggplant shells in oil one at a time for a few minutes per side. The edges and back of the eggplant should blister slightly and get a little bit soft.
Allow the eggplant shells to cool slightly so they can be easily handled. Meanwhile, heat the tomato sauce in a saucepan until warmed nicely.
Pour a small amount of the heated sauce in the bottom of a 13x9 glass pan. (Just enough to lightly coat the bottom of the pan).
Once eggplant shells are cool enough to handle, stuff each one with the eggplant and ground turkey mixture. Place the shells face down in the prepared 13x9 pan.
Spoon the remainder of the sauce overtop of the eggplant and cover the dish with foil.
Bake at 350 degrees for 60-90 minutes until tender and meat is cooked through. (165 degrees)
