(No amounts given, just use amount needed for your family)
Yellow summer squash, peeled, seeded and cubed
Roma tomatoes, cored and cut in chunks
Red, yellow or green pepper, (or some of each), cut in chunks
Yellow or white onion, cut in chunks
Shredded fresh Parmesan cheese, (not the kind that comes in those plastic shakers)
Olive oil cooking spray, (or small amount of any oil)
Seasoned salt, oregano, black pepper
Grease or spray bottom of baking pan, (I used a 9x9 metal cake pan). Put a layer of squash in the bottom and season lightly with spices. Sprinkle with cheese. Top with a layer of each of the other vegetables, again season with spices and top with more cheese.
Bake at 400 degrees until veggies are heated through, cheese is melted and vegetables are done to your preference.
I baked mine for 45 minutes and they were very tender, which is what I was aiming for.
You could easily substitute other kinds of squash.
