To make 12 Dino eggs, you will need six hard-boiled eggs. Peel the shells from the eggs. Slice each egg in half and carefully scoop out the yolk. Mix the yolks with 1 tsp. prepared mustard, 2 Tbs. mayonnaise, and 3 drops of your child’s favorite food color. Mash ingredients together with a fork until smooth. Scoop the yolk mixture evenly into each egg white half. Refrigerate until serving time. Your little dinosaurs will gobble them right up!
