To begin, prepare your fruit. Peel the skin of both the kiwi and mango. A potato peeler works well for this. Chop the fruit into small pieces, around 1/2 inch in diameter.
Layer your fruit in the bowl, and then toss to combine altogether.
Prepare the syrup: Chop the basil into small fine pieces, squeeze the juice of 1 lime, and grate the lime peel using a microplane zester. Add honey, and whisk together to combine.
Pour syrup over fruit, and stir to coat. Serve immediately, or chill for up to 8 hours before serving. This salad tastes best served within the 8 hour window, but can still hold up for a few extra days in the fridge.
