Ohmehgawd! These are fantastic (apologies for the bad photo)! They are from Isa Chandra's Isa Does It book, and are the Bistro Beet Burgers (p82). They are flavorful, they do what few veg burgers do- coagulate nicely, and they aren't a boat load of work. I made "slider" size burgers to be sure that they cooked all the way through and made them on a cast iron skillet (which I am forever loyal to). These were also served up on pretzel buns (or a sliced pretzel baguette), which elevates any burger to amazing heights (ala Kumas Korner in Chicago <3 )
