  6. Transfer the squash mixture into prepared baking dish. 
  7. In a separate bowl, combine crushed butter  crackers, parmesan cheese and two tablespoons melted butter.
    Sprinkle cracker crumb mixture over top of casserole.

For an extra festive casserole, add chopped pimento to the egg mixture for a little color. Garnish with fresh chopped Italian parsley.
