Set oven to 180C . To make this dish easier, I used a dish to mix the chicken breasts, potatoes and carrots in while I coat them all with the jar of chicken tonight.

Pop all the ingredients into the roasting bag and seal it well.

Lay your chicken out so that each piece is separate and on the floor of your roasting tray. If they are piled on top of each other, they will not cook properly. This is why you need a large roasting bag. If you only have smaller ones, split your ingredients into smaller batches.

Cook in the oven for an hour, or until the chicken breasts are fully cooked. This could be more or less, depending on how large your chicken breasts are.

Just take out of the bag and serve. Easy Peasy.
