2Tablespoonsgrapefruit juice(leftover from peeling the grapefruit)
Add olive oil to saucepan over medium high heat. Add garlic and cook for 30 seconds.
Add shrimp and saute for a few seconds, just until pink on both sides (don't over cook!).
Peel the rind off the grapefruit. Halve it, and then remove the skin from each individual slice so that your just left with slices of grapefruit flesh. Do this over a plate, and save any juice that accumulates on the plate.

Top with cooked shrimp. Pour desired amount of dressing on top.
For the dressing, whisk all ingredients together in a bowl until well combined.
