Pesto Balsamic Mozzarella Panini

This was one of those days when I wasn't sure what to make for lunch, but just happened to have a group of tasty complimentary ingredients.  I usually have pesto, onion, lettuce, bread, and sun-dried tomatoes.  This day I happen to have some fresh mozzarella to tie it all together.  I would normally use whole wheat bread, but I happen to have some pesto bread from the farmer's market so I used that.  I sprinkled a little bit of balsamic vinegar on the bread for an extra touch of deliciousness.  I used a panini maker to toast it, but you can also turn the oven on to broil and turn once after about 2 minutes, then broil 1-2 more minutes.
