Slice off the grapefruit peel and pith exposing the fruit.
Cut the fruit into segments (hold on to any juices). Set aside.
Peel the mango (I use a vegetable peeler) and slice alongside the pit to each side.
Cut each mango half into long strips (widthwise).
Spread out the mango slices with equal distance.
Peel, halve, and pit the avocado.
Slice the avocado halves into thin strips widthwise.
Spread out the slices with equal distance so the avocado now resembles one long strip.
Tuck and roll the avocado into a rose-shape.
Transfer the avocado rose using a wide knife or spatula.
Place the mango slices around the avocado rose in a circular shape.
Arrange the grapefruit segments in two layers.
Place the top segments between the bottom segments to create a flower design.
Mix the ingredients for the dressing: the olive oil, grapefruit juice, apple cider vinegar, honey, lemon juice, and chopped mint.
Season well.
Spoon over the salad.
Sprinkle with chopped pistachios. Serve.
