Day #91 - Grilled Cheese Burger

I took a leftover hamburger patty from last night and sliced it horizontally in half.  I placed the halves in a skillet and heated them up on both sides, and then put the halves in between 2 slices of whole grain bread with mozzarella and swiss cheeses, and a spread of ketchup.  Grilled the sandwich until toasty brown on both sides.   (I didn't have any onions, otherwise I would have grilled those and added them too)
