These mock "Hamburger" buns are amazingly bread-like in texture (and taste!) and are suitable for all phases of The Dukan Diet! Once completely cool, seal them in a ziplock storage baggie or a tupperware over night. They will totally change their consistency, to something much more like bread - a softer texture that is nice and chewy. While warm they are crumbly and similar to cooked meringue - but don't let this fool you! Since the sides that were facing the pan are perfectly flat, you use these to spread things on, or make sandwiches, or even as a burger bun! My favorite is spreading cream cheese on both sides (like a sandwich) and stuffing with a freshly poached egg...delish!
