Bring a pot of salted water to a boil, add shrimp, and cook for 2 to 3 minutes until pink and opaque.

Drain shrimp immediately and transfer to an ice bath to stop the cooking process; once chilled, drain and pat dry.

In a large mixing bowl, combine the sliced cucumbers, red onion, and chilled shrimp.

In a small bowl, whisk together the olive oil, lemon juice, minced garlic, salt, and pepper.

Pour the dressing over the shrimp and cucumber mixture and toss gently to coat evenly.

Garnish with fresh dill and serve immediately or refrigerate for up to 30 minutes to enhance flavors.
