In a large bowl, toss pasta, tomatoes, chickpeas, sausage, and bocconcini together.
In a small dish, whisk together garlic, olive oil, and vinegar to make dressing.
Add dressing and basil to other ingredients and toss together. Sprinkle with salt and freshly cracked pepper to taste.
Notes
Leftovers will keep in the refrigerator for up to 2-3 days because the dressing is made with fresh garlic. If stored longer there is a risk that the garlic, which has extremely low acidity, may produce botulism, a serious toxin, and that is not a risk worth taking.
