Instruction

• 15 minute potato gratin with chicken and bacon greens: a gratin always seems more effort and more indulgent than ordinary boiled or roasts, but it doesn't have to take 45mins, it's nice for a change and you can control the calorie content by going with full fat to low fat creme fraiche
• (It's always tastes better full fat though obviously!) to serve 4: use 800g of potatoes, finely slice and boil in a pan for about 5-8 mins till firmish, not soft
• Finely slice 3 onions and place in an oven dish with 2 tblsp of olive oil and 100ml of chicken stock
• Cook till the onions are soft then drain the potatoes and pour onto the onions
• Season and spoon over cream or creme fraiche till all is covered but not swimming
• Grate Parmesan over the top then finish under the grill till nicely golden
• serve with chicken and bacon, peas and spinach
