Disgusting...
However, I did see a program on the Food Network once that did a profile on a grourmet burger restaurant in Las Vegas. They did a dessert burger that used Krispy Kreme donuts for the buns (or some other similar glazed variety), a hunk of chocolate ganache for the "meat," strawberries for the "tomatoes," and mint for the "lettuce." Now that I could enjoy, especially now with my pregnancy cravings!
