While the cabbage is cooking, in a large skillet over medium-high heat add 2 tbsp of olive oil and 2 tbsp of butter to the pan.
Add grated onion and sauté for about 3 minutes. Next add the grated carrot and sauté for another 5 minutes or until softened.
Add 2 cups of cauliflower rice to the carrot and onion mixture and sauté for a few minutes.
Finally add 1 cup of tomato sauce to the skillet and cook for about 2-3 minutes.
Once done cooking, remove skillet and allow the filling to slightly cool.
In a large mixing bowl, add ground meat, 2 eggs, 1/2 tsp salt, 1/2 tsp of chicken & pork seasoning, and 1/4 tsp of ground pepper. Mix thoroughly.
Once carrot and onion mixture has slightly cooled, add it to the meat mixture and combine thoroughly.
