Prep the produce. Peel and dice the mango into bite-size cubes. Slice the bell peppers and red onion thinly.
If using cucumber, halve lengthwise and slice. Mince the jalapeño, removing seeds for less heat.
Mix the dressing. In a small bowl, whisk lime juice, olive oil, honey, cumin, a pinch of salt, and a few grinds of black pepper. Taste and adjust—add more lime for tang, more honey for balance, or more salt if it tastes flat.
Toss gently. Add mango, peppers, onion, cucumber, jalapeño, cilantro, and mint to a large bowl.
Pour the dressing over the top. Toss gently with a spatula or clean hands to avoid crushing the mango.
Rest briefly. Let the salad sit for 5–10 minutes so the flavors meld. This brief rest helps the onion mellow and the mango absorb the dressing.
Finish and serve. Taste again.
Add salt or lime as needed. Sprinkle with toasted pumpkin seeds or peanuts for crunch if you like, and serve chilled or at cool room temperature.
