This delectable low-calorie chicken dish is packed with flavour but not calories and is perfect for anyone following the 5:2 Diet as well as Weight Watchers. It's a favourite meal for me and my husband when we are on a diet, when I serve it with lots of steamed greens and a grilled tomato. For a gluten free version use crushed cornflakes in place of the breadcrumbs. NB: Please note these don't have any oil brushed on them as they are for a very low-calorie diet! If you are NOT worried about the extra calories, please brush the chicken fillets with a little oil before baking, or pan-fry them in a little oil or butter.
