Preheat oven to 400 degrees. Slice your eggplant lengthwise. Then with your knife start to core out the centers where the seed & flesh are. Leave about 1/4-1/2 of an inch around the sides of the flesh. ( tip: flip the egg plant over and slice a bit off the round bottom, in order to have them eggplants lay more flat on the baking sheet)

Spray with olive oil baking spray and sprinkle with pizza seasoning. Bake for 10 minutes at 400 degrees.

While your eggplants are baking you will start on your deep dish filling. In a medium sized frying pan add olive oil, minced garlic, chopped onion and sauté for 2 minutes. Then add in the fresh spinach and cook down. You may need to add it in batches, the spinach will wilt down fast. Once all the spinach is cooked down, add the jar of pizza sauce and mix until full incorporated.

Once the eggplant is done baking, evenly distribute the deep dish filling in each half of the eggplants. Then sprinkle with cheese. Add any of the other toppings you'd want too, like sliced black olives, pepperonis, onions, green peppers etc.

Place back in the oven for 15 more minutes. Then place on high broil for 2 minutes or until the tops start to get nice and bubbly.

Take out of the oven, sprinkle with parmesan, slice and enjoy!
