Grilled Cheese Caprese Sandwiches

"the ultimate caprese grilled cheese sandwiches - because they’re too good and too simple not to make! sweet cherry tomatoes cooked down with shallots + garlic + thyme, mounded on top of LOTS of mozzarella cheese, and cooked between two pieces of fresh bread that crisp up in bubbling olive oil. & some torn fresh basil leaves, of course😍"
