Left-over mashed potatoes are good enough just as left-overs, but here are a few ideas for other things:

• Make potato soup.  Heat mashed potatoes in a saucepan and add milk to make it the right consistency for soup.  Add salt, pepper, and a little olive oil or butter.
• Make potato patties.  My mother used to make these while I was growing up.  Simply form a pattie out of the mashed potatoes and fry in oil (olive oil) and add salt and pepper.

• Make potato salad.  Just add your favorites such as mayonaise, mustard, chopped onion, chopped hard-boiled eggs, chopped celery, etc.
• Make Shepherd’s Pie.  This idea is from Lynne, The Sewing Mom.   Thanks, Lynne!
