Preheat your oven to 375 degrees
Slice the eggplant, zucchini and tomatoes into 1/8” slices and set aside for now
Place a 10” oven proof skillet over medium heat
Add 2 tablespoons of olive oil, 5 cloves of finely minced garlic, 1 large finely minced shallot and 1 finely minced sweet bell pepper and cook until the sauce is fragrant and the peppers are tender (6-8 minutes)
Add 28 ounces of crushed tomatoes, 1 teaspoon of dried oregano, 1 teaspoon of dried basil, 1 teaspoon of dried parsley, a pinch of red pepper flakes and a big pinch of salt and black pepper and simmer for about 5 minutes
Taste to see if additional salt or black pepper is needed and then transfer the skillet off of the heat
Stack the thinly sliced vegetables in an alternating pattern over the tomato sauce and brush with olive oil
Cover the skillet with foil and bake in a 375 degree oven for 30 minutes
Remove the foil and continue baking until tender and bubbly
Garnish with fresh parsley, a light sprinkle of salt and shredded parmesan
