Roasted Pepper Caprese

Name: Roasted Pepper Caprese
Ingredients: 3 lb. mixed bell peppers and chiles (any more than 2 hot chiles and the peppers will end up spicy, which is delicious as long as that is what you are going for; a handful of shishitos are great in the mix as well), large peppers seeded, cut off of cores into quarters; 6 garlic cloves, lightly crushed; ⅓ cup extra-virgin olive oil; Kosher salt, freshly ground pepper; 12 oz. fresh mozzarella; Basil leaves (for serving); 1 Tbsp. white balsamic vinegar
