Combine the black beans, mango, red bell pepper, red onion, red cabbage, and cilantro in a large bowl.
In a small bowl, whisk together the lime juice, olive oil, salt, and pepper.
Pour the dressing over the salad and toss gently to combine. Chill in the fridge for at least 30 minutes to let the flavors mingle (if you can wait!).Serve and enjoy!
