Another recipe from my grandma. :) I absolutely love sweet potatoes and don't just eat them for Thanksgiving. While most people think of having this with turkey as part of all of the trimmings, it is absolutely wonderful served with roasted chicken for a Sunday dinner.
6 medium sweet potatoes
1/2 cup crushed pineapple
1/2 cup chopped nuts
Wash and boil potatoes. Remove skins and mash potatoes. Add crushed pineapple and nuts. Place in a greased casserole dish and cover with marshmallows. Bake at 350 degrees for 30-40 minutes or until marshmallows are melted and slightly brown.
