Combine the sliced cucumber and water in a pitcher. Refrigerate while preparing the meal. Add ice just before serving, if desired.
Preheat the oven to 425°F (218°C). Line a baking sheet with parchment paper.
Place the sweet potato tater tots in a single layer on the baking sheet. Bake according to the package directions.
Whisk together the Greek yogurt, milk, lemon juice, dill, parsley, garlic powder, onion powder, and black pepper. Refrigerate until ready to serve.
In a bowl, combine the chicken strips, olive oil, black pepper, garlic powder, smoked paprika, and onion powder. Toss until the chicken is evenly coated.
