I love making eggplant florentine. Here's what I do: peel it, slice it into 1/4" rounds and sprinkle both sides with salt to draw out the moisture (about an hour). Then I wipe the salt away and pat dry with paper towels.
In a shallow dish, I mix egg substitute and skim milk, then dip the eggplant in before dredging in instant potato flakes seasoned with Italian seasonings (sounds odd, but so yummy and bakes up crispy). Lay breaded eggplant on a baking sheet and bake at 400F for 20 minutes or 'til golden (turning over halfway through for evening browning).
When done, I spray a baking dish with non-stick spray and add a layer of spaghetti sauce to the bottom of the dish. Then I arrange a single layer of eggplant and top with a mixture of low-fat cottage cheese, chopped spinach (fresh or frozen and well drained), and garlic. Repeat the layers (sauce, eggplant, cheese) finishing with eggplant. Pour more spaghetti sauce over the top and sprinkle with part-skim mozzarella. Cover and bake at 375F for 45 minutes, then uncover and bake another 15 minutes to brown the cheese.
Serve with your choice of salad, minestrone soup, veggies and/or garlic bread. I make a big tray of this and freeze individual servings to bring to work for lunch. It's reeeeally good!
