Select fine lemons,wipe carefully,scoop out the pulp,remove the tough inner skin and seeds,and to the rest add one box of boneless sardines,finely chopped,one teaspoon of French mustard,two hard-boiled eggs chopped,some tabasco sauce,and mayonnaise. Fill each cup with the mixture. Cut a small slice from the bottom of the lemon,so that it will stand firmly. Garnish with chopped egg and chopped parsley,and serve on lettuce leaves.
