Place the eggs in a small saucepan. Fill with enough cold water to cover them by 3 inches. Bring to a boil. Cover and remove from heat. Let stand for 15 minutes. Remove the eggs to a bowl of ice water to cool. Peel the eggs. Chop the whites only, saving the yolks for another use. In a small bowl, combine the egg whites, tomato, parsley, oil, and pepper. Serve with crackers.
