While sauce is simmering, *place cabbage in a covered microwave-safe dish core side down with 1/2 cup of water. Microwave on high for 5 minutes.
Carefully flip over cabbage and cook on high for another 10 minutes. Allow to cool, drain water.
Carefully peel 10 - 15 leaves off one at a time, cutting where the leaf end meets the core.
Lay leaves flat on a surface. Use small knife to cut a V-shaped notch to remove the thick part of the cabbage rib.
Mix all ingredients together- ground turkey, rice, onion, celery, carrot, garlic, egg, dill, parsley, paprika, salt, and pepper. Add 1/2 cup of tomato sauce. Stir to combine.
Preheat oven to 350°. Spread out 1/2 cup of tomato sauce in bottom of 9 x 13" casserole dish.
Shape ⅓ cup of the meat mixture into a small log shape and place into center of a cabbage leaf. Bring in the sides and roll tight. Place seam side down into casserole dish.
Repeat until all the meat mixture is gone, tightly packing in cabbage rolls. Top with remaining tomato sauce.
Cover tightly with foil. Bake 60 - 90 minutes until cabbage is tender and meat cooked.
Allow to cool for 10 minutes before serving. Top with more chopped parsley and dill if desired.
