Wash and hull the strawberries, then quarter them. Peel and chop the pineapple, and slice the kiwis. Rinse the blueberries and drain the mandarin oranges. Combine all fruits in a large mixing bowl.

In a separate bowl, mix the key lime yogurt with the lime zest, lime juice, and honey until smooth and creamy.

Pour the dressing over the fruit mixture and gently toss to coat without crushing the fruit.

Transfer to a serving bowl and garnish with lime zest or mint leaves if desired. Serve immediately.
