chop two onions and sauté in cooking spray and a little water until they begin to caramelize
peel and slice an eggplant thinly & soak for 30 minutes in salted water
spray a loaf pan with PAM. Place some onion on the bottom then a layer of eggplant two slices thick then tomatoes. Repeat. (you could add a layer of sliced mushrooms if you like)
season with salt, pepper, and oregano (use garlic powder if you wish)
bake at 350 for about 50 minutes
Can be served warm or at room temp. It's really wonderful.
