Start by preparing the cucumber, mango, bell pepper, and onion. Julienne the cucumber, dice the mango, thinly slice the red bell pepper, and finely chop the red onion. Place all prepared ingredients into a large mixing bowl.
In a smaller bowl, whisk together the lime juice, honey, and sesame oil until combined to create a dressing. Add a pinch of salt and pepper to the dressing, adjusting to taste.
Pour the dressing over the salad ingredients in the mixing bowl.
Add the minced jalapeño for spiciness and fresh cilantro for a burst of flavor. Toss everything gently until the salad is evenly coated.
Let the salad sit for about 10-15 minutes to allow the flavors to meld together.
Before serving, taste and adjust the seasoning with more salt, pepper, or lime juice if needed.
If desired, sprinkle crushed peanuts on top for added crunch just before serving.
Notes
Serve in a large, shallow bowl with a sprinkle of fresh cilantro on top and crushed peanuts on the side for guests to add if they desire.
