Start by washing and chopping your tomatoes into bite-sized pieces, placing them in a large mixing bowl. Add the torn mozzarella, along with a generous handful of fresh arugula. If you’re including any optional add-ins like grilled chicken or beans, toss them in now.

In a small bowl, whisk together ¼ cup of balsamic vinegar and ½ cup of olive oil until it’s well combined. Optionally add salt and pepper to taste.

Drizzle the dressing over the salad ingredients and gently toss everything together until well coated.

Transfer to a serving dish and let the salad rest for about 5 minutes before serving.
