Creamy Cucumber Shrimp salad

In a large bowl, combine Greek yogurt, mayonnaise, lemon juice, Dijon mustard, and chopped dill. Mix well.
Add the cooked shrimp, sliced cucumbers, and red onion to the bowl.
Gently toss the ingredients together until the shrimp and vegetables are well-coated with the dressing.
Season with salt and pepper to taste.
Chill in the refrigerator for at least 30 minutes before serving.
