Learn how to make stuffed burgers and sweet potato fries for your next get together. Take your ground beef and separate it into the appropriate sized balls and patties. Using a patty to start, work an indent in the middle, and fill with mushrooms and a slice of cheese. Then, taking another hunk of the ground beef, cover the top, and work the meat together so that you can't see what's inside. You can use this technique with onions or any other filling you like with your burgers. While the hamburger is cooking, you have the perfect amount of time to cook up some sweet potato fries! Follow this tutorial, and you'll have a fun and tasty meal to share with your family and friends.
