01 - Preheat oven to 375°F. Lightly grease a baking dish with cooking spray or butter.
02 - Lay turkey breast slices flat on a clean work surface, ensuring they are fully flattened for easy rolling.
03 - Place 2-3 tablespoons of prepared stuffing in the center of each turkey slice. Top with half a slice of provolone or mozzarella cheese.
04 - Roll each turkey slice tightly around the stuffing and cheese filling. Secure with toothpicks if necessary to hold the shape.
05 - Place the roll-ups seam-side down in the prepared baking dish, spacing them evenly for uniform cooking.
06 - Pour the turkey or chicken gravy evenly over all the roll-ups, ensuring each piece is coated.
07 - Cover the baking dish tightly with aluminum foil. Bake for 25 minutes to steam and tenderize the turkey.
08 - Remove the foil and continue baking for an additional 10 minutes, or until the turkey reaches an internal temperature of 165°F and is cooked through.
09 - Sprinkle with fresh chopped parsley just before serving, if desired. Serve immediately while hot.
