Reviews forThree-Cheese Florentine Burgers
"Juicy burgers! Turn burgers with a spatula, but don't press them down. It squeezes out the juices, making them dry."
"Awesome! I didn't have asiago cheese so I subbed italian cheese and used provolone slices instead of mozzeralla to top the burgers. Also, used venison burger - you couldn't even tell that it wasn't ground beef!"
