My kids love chips and would have them every day if they were allowed. However, I don't like the high fat content so I make my own low cost version.
I peel the potatoes and cut them into thick slices, then boil them for 10 minutes. I then put a small amount of olive oil on a baking tray and spread over with a pastry brush. Then I place the potatoes on it and put them in a very hot oven (about 220) for 20-30 mins (if you like them more crispy leave them in longer). The kids love them and I could be happy knowing they had less oil on, and no added salt.
I often serve them with fried mushrooms, peas, salad and nut cutlets, or lentil burgers with brocolli, carrots and kale.
