In a blender pulse roughly cubed bread slices, olive oil onion & sage powders, salt and pepper, until you get a crumbled texture.

Transfer to a heat proof bowl, add the panko bread and stir it to combine evenly.

Pour over the mixture hot water, and stir well to allow every piece to be well coated and wet. Set aside for a few moments.

Meanwhile oil a 20x20 oven dish and preheat the oven at 200°C (390° F).

Spread an even layer of the mixture onto the tray, rough up the top, spray with some more olive oil and bake for 25-30 minutes or until golden. Alternatively you can form stuffing balls and cook for ½ of the time.
