Heat the olive oil in a large pot over medium-high heat. Add the onion and cook, stirring occasionally, until the onion is soft, about 5 minutes. Add the bell peppers, carrot and garlic and cook until the vegetables are soft, about 6-8 minutes.Add the tomato paste, sea salt and oregano to the pot and let it cook for 2-3 minutes. Add the crushed tomatoes and the honey to the pot, reduce the heat, and let it simmer gently until the eggplants have finished roasting.While the sauce is cooking, prepare the eggplants. Preheat your oven to 375 degrees. In a medium sized bowl mix the panko, oregano, black pepper and sea salt. Pour the milk into another bowl. Dip each eggplant round first into the milk, and then into the panko. Using one hand for the milk and the other for the panko will make this a lot less messy. Place the panko coated eggplant round onto a baking sheet. Bake the eggplant in the oven for 20 minutes.Spread a couple small scoops of the tomato sauce in the bottom of an 11x9 inch baking dish. Lay half the eggplant rounds over the sauce then cover with half of the remaining sauce and half of the cheeses. Finish assembling the vegetarian eggplant parmesan with the remaining eggplant, sauce and cheeses. Bake in the oven for 40 minutes, or until it is hot and bubbling.Remove the vegetarian eggplant parmesan from the oven and let it rest for 10 minutes before serving.
