If you want to change the flavor, sprinkle a cup of shredded cheddar cheese or any shredded cheese you love into the casserole or the Ritz cracker crumbs ... dish with non-stick spray.

In a small saucepan over medium heat, melt 5 tablespoons butter. Pour Ritz crackers into a medium bowl, and crush into coarse, uneven crumbs. Pour melted butter over crackers and mix to combine.
