Potato Soup (Jenn)

5 lb. bag potatoes (usually Russet); 2-3 stalks celery (sliced); green pepper (diced); bag carrots (sliced); 1 small onion (chopped). Cook until all vegetables are mushy. Mash.

Add: milk (so that it almost fills the pot); margarine; salt and pepper. Cook until thick. The longer cooked, the better it tastes.
