Hodgepodge

This was a leftover dish that Mom liked to make. She had to plan ahead in order to have the right leftovers from three preceding meals:

• Monday: Pork 'n' beans — leftovers became the middle layer of the hodgepodge.
• Tuesday: barbecue quickie — bottom layer.
• Wednesday: Mashed potatoes — top layer.
• Thursday: Hodgepodge: put butter on top of the potatoes and bake in oven
