Hariton's 'Famous' Vegetarian Casserole

Prepare the eggplant before assembling ingredients, by cutting them into 2 inch chunks and putting them into an extra large bowl with salted water to cover. This will draw out the bitterness from the eggplant. Let this sit for about 3 hours.
Preheat oven to 375 degrees F (190 degrees C).
Cut the potatoes, green bell peppers, onion, squash and tomatoes into 2-inch chunks. Cut the green beans and mushrooms in half and peel the garlic cloves.
Drain and rinse the eggplant, then combine it with all the other chopped vegetables, the dill, oregano and basil and place all into a 3x13x18 inch roasting pan. Pour the tomato sauce and olive oil over all.
Bake at 375 degrees F (190 degrees C) for 2 1/2 hours, adding a little water about halfway through cooking time to keep moist.
