Recipe: Cloud's deviled eggs

Hard boiled eggs. Split lengthwise with sharp knife. Use a pointed spoon to delicately remove the yolks.

Mash the yolks with:
mayonnaise
mustard (dry mustard and/or prepared of your choice)
lemon juice (the lemon is the KEY! I make mine pretty lemony)
Salt

Fill the egg shells. Top with paprika

For the "green eggs and ham" part, add green food coloring, and finely chopped boiled sandwich ham.
