1. Cut hard-boiled eggs in half lengthwise. 

2. Carefully remove the yolks into a small mixing bowl. 

3. Mash the yolks with a fork and blend in mayonnaise, salt, pepper and dry mustard and mix well.

4. Using an extra large piping tip, place the egg yolk mixture into a decorator icing bag and pipe it directly into the cavity on the egg white. Alternatively, you can spoon it in carefully with a teaspoon. Another easy option is to put the yolk mixture into a ziplock bag and cut the corner and pipe it in that way for less mess. Either of the three methods will work.
