One of my favorite summer dishes is caprese salad. Sliced tomatoes, fresh mozzarella, basil leaves and balsamic vinegar offer the perfect combination of flavors. It also turns out these ingredients are a perfect grilled cheese in the making! The one issue was the balsamic vinegar–how to incorporate a liquid ingredient on a sandwich that isn’t a dressing? My solution was to simply roast the tomatoes in balsamic vinegar in the oven which infused the flavor of the balsamic into the tomato. I chose sourdough for the bread which worked nicely with the other ingredients. The sandwich was really tasty and not hard to make at all. It was a great way to turn a caprese salad appetizer into the main course!
