In a small saucepan, combine the apple juice, honey, ginger and lemon juice. Bring to a boil over medium-high heat. Cook and stir for 2 minutes or until mixture is reduced to 3/4 cup. Remove from the heat. Cool.
In a serving bowl, combine the cantaloupe, strawberries, blueberries and mint. Drizzle with cooled apple juice mixture; gently toss to coat.
