In a skillet, mix together the meat, seasoning and onion. Cook until browned. Drain.
Stir in the olives and salsa.
Spray a cooking sheet with spray oil. Place one pie crust on it and spread the meat mixture on it. Stop about 3/4" from the edge.
Sprinkle on the cheese. Place other crust on top and seal the edge with a fork. You might moisten the edge to help it stick together better.
Cut a couple of slits in the top.
Bake at 425 degrees for 15 - 25 minutes or until the crust is golden brown.
Serve topped with shredded lettuce, chopped tomato, sour cream, salsa, guacamole, etc.
