Place cherry tomatoes and mozzarella in a large bowl. Drizzle with olive oil (2-3 Tbsp) and vinegar (2-3 Tbsp).
Toss well and spoon onto a large, shallow platter. Season with salt and pepper, to taste, and sprinkle with the fresh basil. Don’t have mozzarella on hand? Try following the recipe with just sliced tomatoes and basil. Enjoy!
