In a large mixing bowl, combine the chickpeas, diced mango, red bell pepper, red onion, cherry tomatoes, avocado, and cilantro.
In a separate small bowl, whisk together the lime juice, olive oil, cumin, salt, and pepper until well combined.
Pour the dressing over the salad mixture and gently toss to combine, being careful not to mash the avocado.
Taste and adjust seasoning if necessary. If desired, chill the salad in the refrigerator for about 30 minutes to allow the flavors to meld.
Serve immediately or store in an airtight container in the refrigerator for up to 2 days.
