Place sliced red onions into a small bowl and add the red wine vinegar. Add a bit more vinegar if needed so it nearly covers the top of the onions. Allow to macerate, uncovered at room temperature, for 20-30 minutes. (Note: This step can be done the night before simply if it is more convenient - the onion flavor mellows out further and they are softer compared to a quick maceration. Delicious either way.)
Whisk all the ingredients together and set aside.
Place the water in a large pot. Add the salt and juice of half a lemon, and bring to a boil. Add the thawed shrimp. Cover pot and remove from heat. Poach the shrimp undisturbed for about 5 minutes, or until they are pink and opaque, and feels firm when gently squeezed. Rinse under cold water to stop the cooking. Drain. Peel (and de-vein if needed). Pat dry.
Toss all the ingredients together with the dressing and serve immediately.
