From Better Homes & Gardens
1/4 C mayo
1 t mustard, I like Woeber's Sweet & Spicy Mustard
1 t vinegar
Hard boil the eggs. I bring them to a rolling boil and boil for 10 minutes. Rinse in cold water then peel the shell off the eggs.
Cut the eggs length-wise and place the egg yolks in a small bowl. Add the mayo, mustard, and vinegar to the bowl and mix well. Put the egg yolk mixture in a sandwich bag. Cut a small piece off a corner and squeeze the mixture into the egg whites. Sprinkle with paprika and watch them disappear.
