Preheat your oven to 180°C and prepare a cast iron or other oven safe pan over medium heat with cooking fat of your choice.
With a sharp knife, butterfly each breast open until it lays flat then flatten with a mallet.
Combine the apple, dried cranberries, walnuts, mushrooms, rosemary, thyme, and season with salt and pepper in a bowl and mix well.
Spread the filling mix on top of each breast nearly up to the edge (as if making a jelly roll).
Roll up each breast tightly and tie with cooking twine.
Season the rolled breasts generously on all sides then place the turkey in the heated cast iron or dutch oven and brown on both sides, about 3-4 minutes each side.
Place the cooking vessel in the oven, uncovered, and roast for about 40-50 minutes.
Allow turkey breast to sit for 5-10 minutes before slicing.
