How to Make It
Preheat oven to 350 degrees. Arrange bread slices in a single layer in an ungreased 13"x9" baking pan; toast bread in preheated oven for 5 minutes and set aside.
In a bowl, combine cream cheese, mayonnaise and seasonings; spread over bread slices. Sprinkle with 1/2 cup cheese; set aside. Gently mix together meatballs, and spaghetti sauce; spoon over cheese. Sprinkle with remaining cheese. Bake, uncovered, for 30 minutes.
