Caprese Panini with Balsamic Syrup

I had some tomatoes, basil, and fresh mozzarella left over from the previous dinner recipe, so this made a delicious lunch sandwich.  You can't see the balsamic syrup in the photo, but it added really nice flavor to the sandwich.

Caprese Panini with Bacon and Balsamic Syrup

Ingredients:
1/4 cup balsamic vinegar
2 slices bread
1/2 tablespoon extra-virgin olive oil
3-4 large basil leaves
2 thin slices fresh mozzarella cheese (just enough to cover bread)
2 slices bacon
2 thin tomato slices
pinch salt
pinch pepper
cooking spray

Directions:
Bring balsamic vinegar to a boil in a small saucepan over medium-high heat and cook until reduced to 1-2 tablespoons (~5-7 minutes).

Brush outer sides of bread slices with olive oil.  Brush the balsamic syrup on the inside of the bread slices.  Top the inside slice with basil leaves, cheese, bacon, and tomato.  Sprinkle with salt and pepper.

Heat a large grill pan over medium-high heat and coat with cooking spray.  Add sandwich to pan and place a heavy skillet on top and gently press to flatten.  Cook 3 minutes each side or until cheese melts and bread is toasted.
