To make Caprese style grilled cheese sandwiches, start by spreading pesto on one side of each slice of bread. Then, layer fresh mozzarella, sliced tomatoes, and basil on top of the pesto on two slices of bread. Top with the remaining slices of bread, pesto side down. Heat a skillet over medium heat and cook the sandwiches until the bread is golden brown and the cheese is melted, flipping halfway through.
