01 - Combine softened cream cheese, Greek yogurt or sour cream, lemon juice, garlic powder, chopped dill, salt, and black pepper in a mixing bowl. Stir until the mixture becomes smooth and uniform.
02 - Lay out the flour tortillas on a clean surface. Evenly spread the prepared dill cream cheese mixture over each tortilla, ensuring it reaches the edges.
03 - Arrange the thinly sliced cucumber in a single even layer over the cream cheese mixture on each tortilla.
04 - Starting from one edge, tightly roll up each tortilla to form a compact log.
05 - Wrap each rolled tortilla in plastic wrap and refrigerate for at least 30 minutes to allow the pinwheels to firm up for easier slicing. This step is optional but recommended.
06 - Unwrap the chilled tortilla logs and use a sharp knife to slice each roll into 6 equal pinwheels. Reserve the uneven ends for snacking or discard.
07 - Arrange sliced pinwheels on a serving platter. Serve chilled or at room temperature as desired.
