To get the sauce, put 1 banana, peeled and cut into circles, half an avocado, a quarter cup of grapes and lemon juice, put in a blender and grind to a puree.
Peel the remaining fruits from the peel (and the grapefruit also from the films), remove the seeds from the mango and papaya.
Cut the remaining grapes in half, cut the avocado into small cubes, and the rest of the fruit into large ones.
Pour dressing over salad and sprinkle with grated coconut.
