Put the eggs in boiling water and cook for about 9 minutes. Drain, rinse with cold water and remove the shell. In the meantime clean and wash the salad, pluck into bite-sized pieces and drain well on a sieve.
Mix vinegar, salt, pepper and sugar. Whip the oil into the mixture. Wash parsley, dab dry and chop finely. Halve the eggs. Carefully lift out the egg yolks with a teaspoon and pass them through a sieve into a small bowl.
Mix with mustard and salad cream. Pour into a piping bag with star-shaped spout and squirt into the egg halves. Clean, wash and quarter the tomato. Arrange two egg halves, some lettuce leaves and one tomato quarter each on plates.
Drizzle the salad with some vinaigrette. Serve sprinkled with parsley and pepper. Garnish with parsley if desired. Serve with wholemeal wheat bread.
