Cut each jalapeno into halves by the length and remove all the insides so only the shell of the pepper remains.
All the filling ingredients should be mixed and spooned into each half pepper.
Season each jalapeno half with the onion powder, salt, red pepper and parmesian.
Bake in the oven at 400 degrees for about half an hour. Bake for shorter to be less crispy and longer for more. Serve hot ideally.
