"This recipe comes from a good friend, and sounds absolutely delicious. For this, I will use a jarred Prego Alfredo sauce. There is a Shortcut provided as an alternate method for pressure cooking the potatoes, and there is three options listed to 'warm' this after it is assembled. You will need several hours ahead of serving in order to make this. The warming is essential to this. Link to the Shortcut is listed in the Recipe Notes section...."
