Slow Cooker Stuffed Cabbage Rolls

INGREDIENTS:

1 head green cabbage
1 pound ground beef
1 cup cooked rice
1 tablespoon onion powder
4 cloves garlic, minced
1 teaspoon salt
1/2 teaspoon black pepper
1 tablespoon Worcestershire sauce
1 teaspoon paprika
1 teaspoon dried Italian herbs
1/4 cup chopped fresh parsley
1 egg

For the sauce:
1/2 onion, finely chopped
4 cloves garlic, minced
1 can (28 ounces) crushed tomatoes, undrained
1 can (15 ounces) tomato sauce
2 tablespoons tomato paste
1/2 teaspoon salt
1/4 teaspoon black pepper
2 tablespoons brown sugar
1 tablespoon red wine vinegar
1 tablespoon Worcestershire sauce
1 teaspoon dried Italian herbs

DIRECTIONS:

In a large bowl, combine the ground beef, cooked rice, onion powder, garlic, salt, pepper, Worcestershire sauce, paprika, Italian herbs, parsley, and egg. Mix until evenly combined.
In a separate bowl, stir together the crushed tomatoes, tomato sauce, tomato paste, onion, garlic, salt, pepper, brown sugar, red wine vinegar, Worcestershire sauce, and Italian herbs. Spray the slow cooker with nonstick spray and line the bottom with a few cabbage leaves. Pour in half of the tomato sauce to make a base layer …
