1. Have all your prepared ingredients ready. Lay out a tortilla on a board or other clean work surface, then spread with the feta cheese and yogurt mixture. Leave a small boarder clear around the edge.
2. Sprinkle the salad veggies evenly all over the cheese, then sprinkle over the oregano and pepper.
3. Roll the tortilla up as tightly as you can, then wrap in plastic wrap. Pop into the refrigerator for about half an hour to firm up a bit.
4. Unwrap the tortilla and chop into about 8 even rounds. To serve, lay out flat on a plate (or stand on their sides and poke through with a cocktail stick---your choice).
*Just multiply the ingredients for as many pinwheels as you need.
