Horizontally halve the turkey breast. Pound with the back of a knife or meat pound to obtain two big flat pieces of meat. Mix the meat with marinade.
Use 1 tbsp oil to sauté garlic and shallots, add chopped mushrooms and stir-fry well. Sizzle wine. Add spinach and toss well with rolled oats to form the fillings.
Sprinkle some flour onto turkey meat, arrange fillings on top, roll and tie up. Repeat this procedure to make another roll.
Pan-fry the roll in 1 tbsp oil until golden. Bake in a preheated oven of 180 degree Celsius for 20 minutes until cooked through. Slice to serve.
