Begin by bringing a large pot of salted water to a rolling boil. Add your choice of small pasta and cook according to the package instructions, approximately 8-10 minutes. Once al dente, drain and set aside to cool slightly.

In a large mixing bowl, combine halved cherry tomatoes, minced garlic, and chopped shallot. Add halved mini bocconcini, olive oil, red wine vinegar, fresh basil, salt, and pepper. Toss gently and let sit for 5-10 minutes.

For optional crunch, toast sourdough bread slices in a preheated oven at 350°F (175°C) for about 10 minutes. Tear into pieces and pulse in a food processor until crumbly. Sauté breadcrumbs in a skillet over medium heat for 3-5 minutes if desired.

Add drained, slightly cooled pasta to the bowl with the tomato mixture. Toss gently until well combined. Taste and adjust seasoning with additional salt or pepper if necessary.

For a refreshingly chilled experience, place the salad in the refrigerator for about 15-20 minutes before serving. Serve cold or at room temperature.
