Make this crisp, fresh tomato salad for your next summer cookout. If you can't find smaller basil leaves, you can gently tear the larger leaves in half.
Combine tomatoes and 1/8 tsp. kosher salt in a large bowl. Let stand 5 minutes. Add basil leaves, olive oil, balsamic vinegar, pepper, 1/4 tsp. kosher salt, and mozzarella; toss.
