I saw this recipe on a cooking show on our local channel and thought it was such a clever idea. Today, I was looking for fun lunch ideas for my kids and thought I'd try it out. You basically bake the hamburger meat in a big rectangle and cut it into squares to make the mini burgers (3 pounds fills a 15x10x1 pan). The buns are simply hot dog buns cut into thirds. They are so cute, and tasty too!
