Heat oven to 200C/180C fan/gas 6. Drizzle the potatoes with the oil and some salt and pepper. Bake on a roasting tray for 25 mins, until starting to go brown.
Remove and turn the chips. Push to edges of the tray, put the gammon in the centre and cook for 7 mins more. Take the tray out of the oven and turn the gammon over, then crack the egg into the corner of the tray. Cook for 7 mins more until the egg is set and the gammon is cooked through. Serve with ketchup, if you like.
