Summer Squash Casserole

While this is a great side dish as is, I added 2 pounds of ground beef to this recipe to make it a full meal and it was very yummy!

2 tablespoons butter
1 large onion, sliced
1 1/2 pounds summer squash or zucchini, sliced into 1/2 inch rounds
1 red pepper, thinly sliced
1/2 teaspoon salt
1 garlic clove, minced
1/8 teaspoon cayenne pepper
2 tablespoons flour
1/2 cup milk
1/2 cup cream
4 tablespoons parmesan cheese, grated
1/2 cup saltine crackers, crumbled (optional)

Preheat oven to 350.  In large skillet, cook onion for 5 minutes, stirring.  Add summer squash and red pepper and salt and cook stirring until tender about 10 minutes.  Stir in garlic and cayenne pepper.  Sprinkle flour over veggies and mix.  Add milk, cream and parmesan and remove from heat.  Put into casserole, top with crackers and more cheese, and bake until bubbling, about 20-30 minutes.
