Prepare the Shrimp : If your shrimp aren't pre-seasoned, sprinkle them with Old Bay seasoning before steaming. Let them cool, then peel and chop them into bite-sized pieces if desired.

Mix the Salad : In a large bowl, combine the chopped shrimp, celery, and onion.

Make the Dressing : In a small bowl, whisk together the mayonnaise, lemon juice, and Old Bay seasoning. Adjust the seasoning to taste.

Combine and Chill : Pour the dressing over the shrimp mixture and toss until well coated. Cover and refrigerate for at least 30 minutes to let the flavors meld.

Serve : Serve chilled on a bed of lettuce, in a sandwich roll, or as part of a summer picnic spread.
