Years ago, we discovered a nifty little invention called The Stufz Hamburger Press. We have been stuffing everything and anything we can into a burger! One of our favorite things to fill a burger with is mac and cheese. The creaminess of the cheese inside the burger will make even a well-done burger still darn tasty. We use box mac and cheese but homemade would surely take this burger to a whole new level. These burgers are so big you will not need a bun.
