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 to halt cooking. 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 dressing over the shrimp mixture and fold gently to coat all components evenly. Refrigerate for at least 15 minutes to allow the flavors to meld before serving.
05 - Plate the chilled shrimp salad over a bed of leafy greens or alongside crusty bread if desired.
