I didn't get a good photo, so will replace next time I make this.
1 lb squash (or more, can use fresh or frozen)
1/2 c chopped onion
2 Tblsp bacon drippings or butter
1 pkg jalapeno cornbread mix
2 eggs, beaten
salt and pepper
1 1/2 cups cheddar cheese
Cook squash and onion in saucepan with water till tender...have at least 1 cup liquid in squash. Mix in drippings or butter, cornbread mix, eggs, salt and pepper. Mix about half the cheese in with casserole ingredients. Pour into a greased casserold dish, and top with remaining cheese. Bake at 350 till brown.
My note: This tastes so much better than my photo above would lead you to believe. It's similar to the squash casserole that is often found on home-cooking type restaurant menus.
