Bring a large pot of water to a rolling boil and generously salt the water. Add the lobster and boil for 3-5 minutes or until the lobster is cooked through.

Remove the lobster tails from the water and add to an ice bath in a large dish. Allow to sit in the ice bath for 5 minutes to cool.

Use kitchen scissors to cut the lobster shells and pull out the meat. Dice the meat into bite-sized pieces and set aside.

Add the pasta to a large bowl. Add the red onion, celery, cooked lobster, mayo, lemon juice, salt and pepper to taste. Toss well to combine and season further to taste.

Top with chives and serve chilled.
