Wash and prepare all fruit.
Place peaches, raspberries, blueberries, and strawberries in a large mixing bowl.
In a small bowl, whisk together honey, lime juice, lime zest, and chopped mint until smooth.
Toss walnuts with honey and a pinch of sea salt.
Toast walnuts in a dry skillet over medium heat for 2–3 minutes until fragrant and lightly caramelized. Allow to cool.
Pour the honey-lime mint dressing over the fruit and gently toss until evenly coated.
Transfer to a serving bowl or platter.
Sprinkle the walnut crunch over the top just before serving.
Garnish with fresh mint leaves and extra lime zest.
