Happy burger season! Over the weekend I made the most amazing lamb burgers. Well, I assembled the patties and my father was in charge of grilling them. "How come there's no cheese?" he wondered while manning the grill. Little did he know that I had already made a whipped feta topping for the burgers. However, I couldn't agree with him more: when it comes to burgers, I can't have one unless it's a cheeseburger. How about you?
