Cut the pita bread into 16 triangles and arrange on a large platter or baking sheet.
Spread a thin layer of the roasted red pepper hummus on one side of each pita triangle.
In a medium mixing bowl mix together the feta cheese, tomatoes, cucumber, olives, pepperoncini, extra virgin olive oil and oregano.
Top each pita triangle with the Greek salad mixture.
Serve immediately or refrigerate in an airtight container.
Notes
These are best served immediately. If you want to make them ahead I would wait to put the Greek salad mixture on until you are ready to serve because the juices can begin to make the pita bread soggy.
