I also like to pour creamy salad dressing on mine.
Here's a good recipe I threw together:
bake some potatoes
cut them in half, scoop out all the potatoey stuff
mash it, mix in about a half-pound of hamburger meat, diced onions, seasonings, butter, and mix well
spoon the mixture into the potato skins, cover with grated cheese, and bake for a few minutes
Mmm-mmm!
