Rinse and dice bell pepper into small (1/4 inch) pieces. Deseed and dice cucumber. Drain and rinse black beans. Chop cilantro.
Pour mango, diced pepper, diced cucumber, black beans and cilantro into a large mixing bowl.
Whisk together rice vinegar, olive oil, honey, chili powder, salt and cayenne. Pour over mixing bowl and toss to coat all of the ingredients in the dressing.
Chill in the fridge and serve or serve immediately at room temperature.
Notes
You can use precut mango but I recommend chopping it into smaller pieces
Feel free to use any color bell pepper
You can use a 1/4 of a jalapeno pepper for extra spice
Serve on its own, alongside fish or with tortilla chips
