Chop potatoes into 1-inch cubes and place in medium saucepan. Cover completely with water and bring to a simmer over medium-low heat. Cook for 20 minutes or until softened through.

Transfer cooked potatoes to a medium-sized mixing bowl. Add remainder of ingredients and stir vigorously with a rubber spatula. The potatoes will break apart and will leave the salad with a mix of smooth, mashed potatoes and chunks.
