Ooo, let's be pedantic! I'm pretty sure I've seen on menus burger-like items containing chicken, called a grilled chicken sandwitch. Now I could be remembering wrong, but I am pretty sure these things were on buns, not normal bread, so that can't be the dintinction. I'm really not sure what makes a burger - maybe the form factor, as you said, but that grilled chicken sandwitch came pretty close. Hmmm....

Nice new layout, by the way!
