Heat up a large non stick frying pan and add half the oil. Using a basting brush, brush egg over the top of the pattie then sprinkle over breadcrumbs and then pat them down neatly with your hand. Using a spatula, loosen the underneath up so it isn't stuck to the chopping board then add it breadcrumb face down into the hot pan. Once it begins to cook, add egg wash and breadcrumbs to the top whilst it's in the frying pan.
