Halloween Eyeball Appetizer

Directions

1. 1
   Place eggs in a single layer in a large saucepan; add enough cold water to cover by 1 in. Cover and bring to a boil over high heat. Remove from the heat; cover and let stand for 15 minutes. Place in ice water until completely cooled. Gently crack eggs (do not peel).
2. 2
   In a large bowl, combine 3 cups hot water, food coloring and vinegar. Add eggs. (If eggs are not completely covered by colored water, add more hot water.) Let stand for 30 minutes. Remove eggs with a slotted spoon; peel.
3. 3
   Cut eggs in half widthwise. Place yolks in a small bowl; set whites aside. Mash yolks with a fork; stir in the mayonnaise, onions, cilantro and mustard.
4. 4
   To level egg white halves, cut a small slice from the bottom of each; place on a serving platter. Pipe or stuff yolk mixture into center of whites. Place an olive slice on each; fill olives with ketchup. Refrigerate until serving. This recipe is best eaten the day it is prepared.
