Follow these simple steps to create your very own Turkey Roll Roast:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Turkey Breast: Lay the boneless turkey breast flat on a cutting board. Use a meat mallet to pound it to an even thickness.
3. Make the Stuffing: In a skillet, heat olive oil over medium heat. Sauté the onions and celery until soft. Add garlic and cook for another minute. Remove from heat and mix in bread crumbs, thyme, rosemary, salt, pepper, chicken broth, parsley, and Parmesan cheese.
4. Stuff the Turkey: Spread the stuffing mixture evenly over the turkey breast, leaving about an inch around the edges.
5. Roll the Turkey: Starting from one end, carefully roll the turkey breast tightly around the stuffing. Secure the roll with kitchen twine at regular intervals.
6. Sear the Roll: In a large oven-safe skillet, heat a bit more olive oil over medium-high heat. Sear the turkey roll on all sides until golden brown, about 3-4 minutes per side.
7. Roast: Transfer the skillet to the preheated oven. Roast for 1 hour and 15 minutes or until the internal temperature reaches 165°F (74°C).
8. Rest: Once cooked, remove the skillet from the oven. Let the turkey roll rest for 15 minutes before slicing.
9. Slice and Serve: Carefully remove the kitchen twine and slice the turkey roll into 1-inch thick pieces.
