1. Preheat oven to 350 degrees F, and grease a cookie sheet. Coat all sides of each potato with olive oil. Place potatoes face down on prepared cookie sheet and bake for about 45 minutes, or until soft (but not too mushy).

2. While the potatoes are roasting, mix the rest of the ingredients (except paprika) together. When the potatoes are done, allow to cool a bit, and then use a sharp knife to cut into the flat side of each potato and then hollow it out with a spoon. You want to be left with a little cup-shaped potato.
3. Add the scooped-out potato to your mayo/mustard mix and blend well. You can then fill the hollowed out potato shells with the mixture piping it on with a cake decorating bag, or do it like he did and just blop it in there. Dust each potato with paprika.
You can refrigerate them for later, or eat them right away like we did! Bring to a potluck and watch your friends grin with delight!
*New potatoes are the very thin skinned potatoes. I've seen them called Klamath Potatoes as well. Try to get ones that are similar in size and shape for uniformity (egg shaped?!).
Source of recipe: My husband was having a Deviled Egg craving, and decided to try making a replica using potatoes instead of hard boiled eggs. I was very skeptical, but quite impressed with the results! It's quite brilliant, actually.
