01 - In a mixing bowl, blend softened cream cheese, Greek yogurt or sour cream, lemon juice, garlic powder, chopped fresh dill, salt, and black pepper until smooth.
02 - Lay the flour tortillas flat and evenly spread the prepared dill cream cheese mixture over the entire surface of each tortilla.
03 - Arrange the thinly sliced cucumber in a single layer over the spread on each tortilla.
04 - Starting from one edge, tightly roll each tortilla into a log. Wrap the rolls in plastic wrap and refrigerate for at least 30 minutes, if desired, for easier slicing.
05 - Remove plastic wrap and use a sharp knife to cut each tortilla roll into 6 even pinwheels. Trim off uneven ends as needed.
06 - Arrange pinwheels on a serving platter and offer chilled or at room temperature.
