I know any photo involving gooey, melted cheese is guaranteed to set your mouth a-watering, but trust me when I say that this sandwich is legitimately one of the most delicious ones that I have ever tasted. There's the fresh mozzarella, broccoli rabe loaded with garlic and spicy red pepper flakes, and a sweet, slow cooked tomato jam, all pressed between a loaf of Italian bread like a crispy panini.
