Prep produce: peel and dice peaches and mango; dice bell pepper and red onion; seed and mince jalapeño; chop cilantro; zest and juice the lime.
In a large bowl, combine peaches, mango, bell pepper, red onion, jalapeño, and cilantro.
Add lime juice, lime zest, kosher salt, cumin, honey, and black pepper. Toss gently to coat without crushing the fruit.
Taste and adjust: add more salt for savoriness, lime for brightness, jalapeño for heat, or honey for balance as needed.
Let the salsa rest for 10 minutes to meld flavors, then serve.
Notes
Serve with tortilla chips, over grilled chicken or fish, or spooned onto tacos. For extra freshness, add diced avocado just before serving. Store refrigerated up to 2 days; drain excess juices and re-season before serving.
