Herby Cod and Baby Potato Tray Bake

This simple, fresh, one pot fish dish is really easy to make, and because it is all done in one pot, it minimises the washing up! Any white fish is really low calorie in comparison to meat, so makes a great swap out when you need to get those calories down.

This dish is around 250 calories, even with the potatoes, so is great for those who have really low calorie allowances. The recipe uses lots of fresh herbs but store cupboard dried herbs will be just as tasty.
