01 - In a mixing bowl, blend softened cream cheese, Greek yogurt or sour cream, lemon juice, garlic powder, chopped dill, salt, and black pepper until smooth.
02 - Place tortillas flat on a clean work surface. Spread dill cream cheese mixture evenly onto each tortilla, ensuring full coverage to the edges.
03 - Distribute cucumber slices in a single layer over the spread on each tortilla.
04 - Starting at one edge, roll each tortilla tightly to form a uniform log shape.
05 - Wrap each rolled tortilla snugly in plastic wrap and refrigerate for at least 30 minutes to firm, ensuring pinwheels slice cleanly.
06 - Remove plastic wrap and use a sharp knife to cut each roll crosswise into 6 even pinwheels. Reserve or use end pieces as desired.
07 - Arrange pinwheels attractively on a platter and serve chilled or at room temperature.
