Place pita pieces on cookie sheet, (don't need parchment paper)
Dab pita pieces with olive oil -- use a pastry brush -- the silicone kind is easiest

Sprinkle a spice mix on top
salt
pepper
Ground Cumin
Thyme
Cayenne Pepper
Sprinkle Sesame Seeds on top

Approx 7 minutes in a 350 degree oven.
No need to flip. They're ready when they have crisped up but are not overly brown.
Make sure they are not limp -- avoid a chewy texture.
