Joan's Leftover Mashed Potato Soup
from Joan, 11/25/01:
Couple of weeks ago I way overestimated the mashed potatoes - so I made the most delicious soup out of them.
Sauteed a bunch of leeks, shallots and garlic (onions and garlic would work fine, or just onions) in butter, sprinkled them with a little flour, added plenty of pepper, stirred in the mashed potatoes and enough milk to the right consistency, then added some grated cheese at the end.
Very satisfying, and the best potato soup I ever had.
