Cook pasta according to package directions. Rinse, drain and combine the pasta and beans in a bowl.
To make the vinaigrette place the vinegar, mustard, garlic, salt and pepper in a bowl. Whisk, slowly add the oil and continue whisking until it thickens. Pour the dressing over the pasta and chickpeas. Cover, let sit at room temperature and allow to marinate for 1 hour or refrigerate for up to 24 hours.
Before serving, add the cherry tomatoes, basil, olives and scallions to the pasta mixture. Toss together and serve on a bed of salad greens.
