Was making a family recipe from leftover mashed potatoes and thought I’d throw this out there. So anyone do anything special with theirs? Been eating this stuff my whole life, they always called it Southern Style Potato Salad. Mix in some mayo with the cold mashed potatoes until it starts getting creamy then add a red wine vinegar till it’s a bit tart. Throw in some chopped green onion to your liking and there ya go. Always made it and French Dip sandwiches with the leftovers from a beef roast.
