Summer perfection

So I can see that great minds think alike, with summer in full swing and tomatoes at their peak I can't think of a better lunch than a tomato sandwich. Although I do like the classic tomato and mayo my all time favorite has an Italian twist.
Start with a nice hunk of sourdough, next add some fresh pesto, then fresh mozzarella, top with garden fresh tomatoes some fresh ground black pepper and sea salt finish with a drizzle of balsamic. Enjoy all the summer flavors at their best.
