Easiest thing you’ll ever do… First, preheat the oven (not the dutch oven) to 450 degrees.
Put the sandwiches together. Lightly brush olive oil on the outside of the bread. Apparently,the word “lightly” means not the way I put condiments on anything. So don’t over-saturate.
Let the oven do the rest. Bake for 5-10 minutes (but check on the sandwich… it’s marathon bread not marathon baking). Bread should be golden and cheese melted.
Cut in half, or in our house we like to make dipping sticks, and serve immediately with the delicious soup!
