Preheat the oven to the temperature stated on the pack of chicken.
Meanwhile, Cut a slit into the side of each chicken breast to make a pocket. Use 6-8 tablespoons of dried stuffing mix and make-up as per the packet instructions. Stuff the chicken pockets with the stuffing mix and reshape your chicken. Then place onto a baking tray (skin side up, if you have chicken breasts with the skin left on).
Then in a small bowl add your thyme and butter and mix well (if you don't like thyme, just use the butter on its own). Rub the butter mix all over the chicken breasts and roast in the oven until the chicken has cooked thoroughly.
Keep basting the chicken with the juices all through the cooking.
Once cooked, serve with a selection of vegetable and your favourite gravy.
