A coworker brought in some mashed potatoes that she put cream cheese & sour cream in with cheddar cheese on top. They were delish!!! You could also try mixing bacon in to add the saltiness you are looking for & some texture. Just experiment with different things...a little Mrs. Dash also could change it up as well!! Good luck!
