Mashed potatoes and cream cheese

Why I Love This Recipe
This wonderful recipe comes from 'Wanda E. Brunstetter's Amish Friends Cookbook', and was submitted by Martha Yoder of Crofton, KY. It goes great with Salisbury Steak, or just about anything for that matter! The recipe called for the potatoes to be peeled, but I left the skins on, because my family and I like our mashed potatoes that way. I used only 1 tsp. of salt.
