Using a strainer, rinse the quinoa under cold water. Add quinoa, water, and salt to a medium saucepan and bring to a boil over medium heat. Boil for 5 minutes. Turn the heat to low and simmer for about 15 minutes, or until water is absorbed. Remove from heat and fluff with a fork. Let quinoa cool to room temperature.
To make the Honey Lime Dressing: In a medium bowl, whisk the lime juice, honey, and mint together until combined.
In a large bowl, combine quinoa, blueberries, strawberries, and mango. Pour honey lime dressing over the fruit salad and mix until well combined. Garnish with additional mint, if desired. Serve at room temperature or chilled.
Note-Use your favorite fruit in this salad. Blackberries, peaches, kiwi, raspberries, pineapple, grapes, etc. are great options!
