I have to admit, I did a terrible job slicing that bread open, but it proves the point that you can mistakes and still come up with something tasty.
Reheating instructions:
Preheat an oven to 400°F (200°C) and place, still wrapped in the foil, for 15 minutes. Flip over and bake an additional 15 minutes. Unwrap, split the bread open, and toast to your desired level of crispiness.
You can also reheat this on a barbecue if you are cooking out! Leave it in the foil and set it on the grill, turning periodically, for 10 to 15 minutes or until heated through completely.
