Prepare 2 boiled eggs and separate the whites from the yolks.
Mash or grind the whites and yolks finely, then mix with one spoonful of Greek yogurt, one spoonful of allulose, and a pinch of salt to make egg salad.
On a slice of whole wheat bread, layer the egg salad, sliced ham, shredded chicken breast, two leaves of romaine lettuce, and another slice of whole wheat bread in that order.
Wrap the sandwich tightly in foil, cut it in half, and it's ready to eat!
