As long as you have a loaf of bread, almost any combination of ingredients can form a panini. In this instance prepare yourself for warm, oozy mozzarella. The flavors of this sandwich are perfect. Instead of using anything too heavy just drizzle the inside of the bread with olive oil and a sprinkling of balsamic vinegar. The dreamy mozzarella perfectly offsets the sweet vegetables and salty jamon. You can find comfort in every single bite.
