This dish is a great time saver, since it can be prepared totally in advance and reheated just before the meal. It's also great because you can play around with the seasonings to suit your family's taste ie: more garlic, or onion, or both! I also think the flavor of these potatoes tastes great using the low fat versions of cream cheese and sour cream. However, when I make these for holiday meals such as Thanksgiving or Christmas, I sometimes use regular sour cream and cream cheese. If I'm using chives for garnish, I like to mix in about 1/4 cup right into the cream cheese/sour cream mixture as I heat it.
