Mix finely chopped chicken, grated apple, sage, salt and pepper together in a bowl.
Using a tablespoon measure, scoop out spooonfuls of mixture and form into 1 x 2 inch nugget shapes. The moist apple helps keep it together.
Dredge the nuggets first in flour, then the egg dip before coating in breadcrumbs. Set aside on a lightly floured baking tray.
Heat oil to 180 C in a large heavy based pan (keep a lid nearby in case of fire).
Fry the nuggets, in batches, for 2-3 minutes each until golden. Drain on kitchen towel and serve immediately.
Notes
Stale ends of loaves can be blitzed in a food processor to make fine crumbs and then stored in the freezer until needed. I always use my breadcrumbs from frozen.
