01 - Combine the softened cream cheese, Greek yogurt or sour cream, lemon juice, garlic powder, chopped dill, salt, and pepper in a mixing bowl. Stir with a spatula or spoon until completely smooth and homogenous.
02 - Lay each tortilla flat on a clean surface. Evenly spread the dill-cream cheese mixture over each tortilla, extending all the way to the edges.
03 - Arrange cucumber slices in a single, even layer atop the cream cheese mixture on each tortilla.
04 - Starting from one edge, roll up each tortilla tightly into a compact log shape.
05 - Wrap each rolled tortilla log in plastic wrap. Refrigerate for a minimum of 30 minutes to allow the filling to set, resulting in cleaner slices.
06 - Remove the chilled logs from the plastic wrap. Using a sharp knife, slice each roll into 6 even pinwheels, discarding or reserving the uneven ends.
07 - Arrange the pinwheels cut side up on a serving platter. Serve chilled or at room temperature.
