Make Ahead: Follow the instructions to make the bread crumb encrusted eggplant coins, but stop before adding the marinara and cheese. Lay the golden brown slices on a baking sheet lined with parchment paper. Once they are room temperature, freeze for about an hour on the tray, and then transfer to a freezer safe bag. When ready to eat, DO NOT DEFROST THE EGGPLANT. Remove the desired number of eggplant slices and top each with marinara, cheese, and toppings. Finish the pizzas off in the air fryer as described in the recipe. You may need to add another 2-3 minutes to the cook time. Breaded eggplant slices will keep up to 3 months in the freezer.
