Cabbage Roll Casserole

2 pounds meatloaf mix
1 large onion, chopped
3 garlic cloves, minced
2 cans (15 ounces each) tomato sauce, divided
1 teaspoon dried thyme
1/2 teaspoon dill weed
1/2 teaspoon rubbed sage
1/4 teaspoon salt
1/4 teaspoon pepper
1/4 teaspoon cayenne pepper
2 cups cooked rice
4 bacon strips, cooked and crumbled
1 medium head cabbage (2 pounds), shredded
1 cup (4 ounces) shredded part-skim mozzarella cheese

In a large skillet, cook the beef, onion and garlic over medium heat until meat is no longer pink; drain. Stir in one can of tomato sauce and seasonings. Bring to a boil. Reduce heat: cover and simmer for 5 minutes. Stir in rice and bacon; heat through. Remove from the heat. Layer a third of the cabbage in a greased crockpot. Top with half of the meat mixture. Repeat layers; top with remaining cabbage. Pour remaining tomato sauce over top. Top with cheese. Cook in crockpot on low for 4-5 hours.
