If you love grilled cheese sandwiches, give this grownup version a try. The balsamic vinegar over the melted mozzarella and fresh basil make for a very satisfying meal.
Preheat oven to 350 F. Assemble your sandwich on a parchment-lined baking sheet, in this order: Bread, cheese, salt & pepper, basil, tomato, bread. Position the sandwich so that the cheese melts down over everything else.
Spray both sides of the sandwich with a light coating of oil using an oil sprayer. You can also spread a light coat of butter on before assembling the sandwich if that works for your eating plan.Fold the sandwich into a piece of parchment, and then sandwich the entire thing between two cookie sheets. (I used two on top because my pans were tiny, and I wanted a little more weight on top.) Set the pan on a wire rack positioned in the middle of your oven.
Bake for about 20 minutes or until the cheese is nicely melted. Remove from oven and remove cookie sheets and parchment. Sprinkle the top of the sandwich with a bit of balsamic vinegar to taste. Cool enough so you don't burn yourself and enjoy.
Note that if you want the bread to be crispier, you can remove the pan and parchment from the top of the sandwich after 15 minutes of baking and turn your broiler on. Just remember to flip the sandwich halfway through the last 5 minutes so both sides get crispy. If your tomato slices are too thick or you put too much cheese on, the bread will be much soggier. So keep it light and simple.
