Sage and Onion Stuffing with Pancetta

1 stalk Celery, chopped
1 Onion, chopped
4oz Pancetta
1/2 loaf white bread, crusts removed
Handful of sage leaves, chopped
1 egg
Olive oil

Put the bread in a food processer and turn it into crumbs. Fry the onion, celery and pancetta in the oil until the vegetables have softened. Add the sage and fry for another minute or two. Add the stuff you've been frying to the breadcrumbs. Season and add the egg. Mix well and stuff the lot into the chicken.
