In a large bowl, toss pasta, tomatoes, chickpeas, salami, and bocconcini together.
In a small dish, whisk together garlic, olive oil, and vinegar to make dressing.
Add dressing and basil to the large bowl and toss everything together. Sprinkle with salt and freshly cracked pepper to taste.
Notes
Leftovers will keep in the refrigerator for no more than 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.
