Balsamic Blueberry Grilled Cheese

This is a delicious, buttery, sandwich with a slightly sweet filling thanks to the blueberries. We used Havarti cheese, but you could use white cheddar or goat (which I definitely plan on trying!) So easy yet so full of flavor. I added basil to the sandwich to give it a reminiscent flavor of a roasted blueberry tart we love:  http://www.colorfulapronstrings.blogspot.com/2014/05/roasted-blueberry-tart.html

Ingredients:
~crusty bread
~Havarti cheese, sliced
~2 tbs fresh basil, chopped
~1/2 cup fresh blueberries
~1 tbs balsamic vinegar
~1 and 1/2 tbs brown sugar
~spreadable butter
~freshly ground black pepper

1. In a small saucepan, combine blueberries, vinegar, and brown sugar over medium heat and bring to a slow boil. Use a potato masher to crush berries. After mixture boils for 5 minutes, pour into a mesh strainer to separate the solids from the juice. (Save the juice - it could be used as a syrup for ice cream, pancakes, you name it!)
2. Heat grill pan over medium heat.
3. Butter outsides of bread. Turn over and layer one slice with blueberries, cheese, basil, and a light dusting
of freshly ground black pepper. Top with other slice and place on grill pan, butter side down. Flip sandwich when bread is toasted. Repeat with other sandwiches.
