Boil the cabbage leaves for 2 minutes, then immediately place in a bowl of ice water, or run under cold water to end the cooking process.
12 large cabbage leaves
In a large bowl, combine the broth, onion, beef, cauliflower, and egg. Mix this together until combined. Add salt and pepper to taste.
1 egg, ¼ cup beef stock, ¼ cup chopped onion, 1 cup riced cauliflower, 1 lb. ground beef
Place the cooked cabbage leaves on a flat surface, and add a spoon of beef toward the base of each leaf. Carefully fold the sides over, then begin rolling away and tucking the cabbage over the beef.
In a small bowl, whisk the tomato sauce and lemon juice to create a sauce. Add salt, pepper, and herbs as desired.
8 oz tomato sauce, 1 tablespoon lemon juice, Sea salt and freshly ground black pepper to taste
Place the cabbage rolls into the Crockpot then top with the sauce.
Cover with the lid and cook on low heat for 6 to 8 hours.
