Healthy egg & chips - had this for tea tonight as part of a fast day. It was really tasty and a substantial amount . Two substitions though - I used low calorie spray instead of oil and cherry tomatoes as I had no mushrooms. Definately be trying this again (maybe as breakfast next time)!
If you know you are going to be pushed on Christmas Day, then it is possible to half-roast the potatoes the day before (see Preparing Ahead, below). On Christmas Day the potatoes just need to be re-roasted in a hot oven for about 20 minutes.
