4 hard-boiled eggs
1/3 c. grated Parmesan cheese
1 tsp. prepared mustard
Pepper
Skim milk
Paprika

Halve the eggs lengthwise; remove yolks and mash. Add the cheese, mustard, few grains of pepper, and enough milk to moisten well. Beat until fluffy and refill the egg whites. May want to garnish with paprika for added color.
