It's all right to be a little devilish during the holidays if it's all in the name of good health and taste. Egg yolks are one of the limited sources of vitamin D, which are naturally available in food. All you need is about 600 IUs (International Units) to reach the daily requirement. We don't suggest you get try to get all your vitamin D from eggs -- at 41 IUs per egg, that'd be a lot of eggs -- but deviled eggs are a party pleaser that'll get you closer to the goal [source: Hand].
Boil a dozen eggs, slice them in half and remove the yolks. Mix the yolks with mustard and mayonnaise, and then scoop a dollop of the mixture into the hollow of each egg white half. Sprinkle with paprika and arrange on a serving tray.
