Danish Egg Salad with Smoked Salmon

This versatile recipe, adapted from my friends Bettina Stern and Suzanne Simon at the cooking website, Loulies, can be eaten as a sandwich, on top of greens, spread on crackers or pita chips, or scooped up with celery sticks.  I love it so much that I eat it right out of the bowl, before it can even make it onto the bread or greens!
