In a small mixing vessel, whisk together the lime juice, lime zest, and honey until the mixture is fully emulsified.
Place the diced Granny Smith apples in a separate small bowl and toss immediately with a teaspoon of the lime dressing to inhibit enzymatic browning.
In a large chilled glass serving bowl, combine the honeydew melon spheres, sliced kiwis, and halved green grapes.
Add the prepared apples to the fruit mixture.
Drizzle the remaining lime-honey dressing over the fruit components.
Gently fold the salad with a silicone spatula to ensure even distribution of the dressing without compromising the structural integrity of the softer fruits.
Scatter the fresh mint chiffonade over the surface for aromatic contrast.
Serve immediately or refrigerate at 40°F (4°C) for up to 2 hours prior to service.
