Creating Cold Cucumber Chicken Salad is simple if you follow these steps:

1. Cook the Chicken: If not using pre-cooked chicken, season chicken breasts with salt and pepper. Cook them in a skillet over medium heat for about 20 minutes until fully cooked. Let them cool before shredding or dicing.
2. Prepare Vegetables: While the chicken is cooking, dice the cucumber and halve the cherry tomatoes. Finely chop the red onion.
3. Make the Dressing: In a large bowl, combine the Greek yogurt, mayonnaise, lemon juice, garlic powder, salt, and pepper. Mix well until smooth.
4. Combine Ingredients: Add the cooked chicken, diced cucumber, cherry tomatoes, and red onion to the bowl with the dressing. Gently toss everything together until well coated.
5. Chill (Optional): For enhanced flavor, cover the salad and chill it in the refrigerator for about 30 minutes.
6. Serve: Once chilled, garnish with fresh dill or parsley before serving.
