Parboil some Maris Piper or Estima potatoes for about 5 mins. Drain and leave in the pan to steam for a couple more minutes. Coat with olive/vegetable oil and season with salt. Place on a hot oiled oven tray and cook for around 30 minutes in a hot oven.
We're having these tonight with egg, beans and mushrooms. Our total meal will come to around 500 calories. Shop bought processed oven chips do not have the same structure and can be higher in calories too. Usually you will find the inside of the chip is processed/mashed. Our home made chips have a good bite to them and we think they are the real mccoy!!
