One of favorite ways to eat squash is just cooked with sweet onions in a little butter. We call it squishy squash. Bill will tell you that I could eat this every day. He is not as excited about my good deal on a bushel of squash as I am.
We also love a good squash casserole. This is an easy recipe that can be made ahead and frozen. 
Squash Casserole
3 cups squash
1 sweet onion
1 cup cheddar cheese
1 cup crushed saltines
1/2 cup ranch dressing
3 eggs
Salt and pepper to taste
Saute squash and onions until tender. Allow to cool. Combine all ingredients in a large bowl. Beat in eggs last. Pour into a 9x13 baking dish. Cover with foil and bake at 350 for 30 minutes.
You can bet I have a couple of casseroles in my freezer right now.
Y'all enjoy!
