Instructions

• Using a sharp knife, cut the skin and all of the bitter white pith off of the grapefruit. Working over a bowl, cut in between the membranes to release the sections. Add those sections to a salad bowl. (You can squeeze the juice from the membranes and transfer all excess juice into a separate glass to drink it later).
• Add shrimps, olive oil and balsamic vinegar to the salad bowl and voilà! Serve immediately.
  Bon appétit!
