Spicy Stuffed Eggs

Cook the eggs, peel and halve lengthwise. Place 1 yolk in a small bowl, discard remaining yolks. Mash the yolk with a fork, then add 4 of the white halves and mash. Mix in the onion, mayonnaise, parsley, pickles, mustard, salt and pepper. Mound the mixture into remaining white halves, dividing it equally. Garnish each half, if desired, with a sprig of parsley. Cover loosely and refrigerate until ready to serve. Makes 8 servings
