For the vinaigrette:

Whisk together the pineapple juice, red wine vinegar, shallot and salt and pepper. Slowly incorporate the canola oil. Taste, for seasoning.

For the salad:

In a large salad bowl, toss together the mango, papaya, cranberries, banana chips and macadamia nuts with 1 cup of the vinaigrette. Season lightly with salt and pepper. Place the mizuna on a large serving tray and top with the mixed fruit. (The salad greens hold up longer if only the fruit is tossed with the vinaigrette. However, if serving promptly, combine the greens and the fruit and toss with the vinaigrette.) Drizzle the salad with the extra dressing or serve on the side.
