This twice baked potato recipe is a great use of those leftover mashed potatoes. Adding onion to the mix and a generous coating of cheddar cheese really breathes new life into the potatoes, which may have suffered a different fate.
If desired add chopped chives instead of onions and serve with a dollop of sour cream. Or add crunchy bacon bits, once plated.
