Quick potato soup

Still have leftover mashed potatoes from Thanksgiving? Use them this way:

* 2 cups of leftover mashed potatoes
* 2 tablespoons of dehydrated onions
* 1 small can evaporated milk or 1 cup of milk to which you've added 1/3 cup of instant milk powder.
* salt, pepper to taste
Put the onion in a cup or so of water, and set to simmer. Add about half the milk and mix into the potatoes well, then add to the onions. Add water if it seems to thick, then let the mixture simmer until the onions are tender. Add the rest of the milk and salt and pepper to taste.

Serve with corn bread or homemade yeast bread.
