In a small bowl, combine 1/2 cup plain Greek yogurt, 1 tablespoon olive oil, 2 teaspoons lemon juice, 1/4 teaspoon salt, and 1/4 teaspoon black pepper. Stir well.
Add 1 tablespoon minced fresh dill, 1 clove minced garlic, and 1/2 diced cucumber to the yogurt mixture.
Stir all ingredients until thoroughly combined and smooth.
Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld before serving.
