Start by washing all the fruits thoroughly under cold water. Hull and slice the strawberries, dice the pineapple, halve the grapes, peel and slice the kiwi, and segment the mandarins. Place all prepared fruits into a large mixing bowl.
In a small bowl, whisk together the honey, freshly squeezed lime juice, lime zest, and vanilla extract. Stir until the honey fully dissolves and the dressing looks smooth and glossy.
Pour the honey lime dressing evenly over the mixed fruits. Using a large spoon or spatula, gently toss everything together until all fruits are lightly coated without being mashed.
Cover the bowl and refrigerate the fruit salad for at least 30 minutes. This resting time allows the flavors to blend and makes the salad more refreshing.
Give the salad a gentle stir before serving. Taste and adjust with extra lime juice or honey if needed, then serve chilled.
