Wash all produce thoroughly. Dice the mangoes and cucumber, chop the red bell pepper, slice the red onion thinly, and chop the fresh cilantro. Set aside in a large mixing bowl.

In a small bowl, whisk together lime juice, fish sauce (or soy sauce), honey, and chili flakes until well combined.

Pour the dressing over the chopped vegetables and fruits in the mixing bowl. Gently fold the ingredients together, being careful not to mash the mangoes.

Let the salad rest for 10 minutes to allow flavors to meld.

Serve chilled or at room temperature, garnished with additional cilantro if desired.
