In a large bowl, add the chickpeas, roasted bell pepper, parsley, celery, and red onion. In a small jar with lid, add the infused olive oil, lemon juice, salt, and garlic. Shake vigorously. Season to taste with additional salt if preferred. Add the dressing to the chickpea and veggies mixture and toss to coat evenly. Serve immediately or chill up to 2 days. Before serving, stir mix again.
