01 - Bring a pot of salted water to a rolling boil. Add the shrimp and cook for 2 to 3 minutes until pink and opaque throughout. Drain immediately and rinse under cold running water. Pat dry with paper towels.
02 - In a large mixing bowl, add the cooked shrimp, sliced celery, diced red onion, diced cucumber, halved cherry tomatoes, and chopped dill. Toss gently to distribute evenly.
03 - In a separate small bowl, whisk together the mayonnaise, Greek yogurt, Dijon mustard, lemon juice, lemon zest, salt, and black pepper until smooth and fully incorporated.
04 - Pour the prepared dressing over the shrimp and vegetable mixture. Fold gently with a large spoon until all ingredients are evenly coated.
05 - Refrigerate the salad for at least 15 minutes to allow the flavors to meld. Serve chilled on a bed of leafy greens or alongside crusty bread if desired.
