Using a large dutch oven, brown the ground beef on medium heat and lightly season with salt and pepper. Remove the beef and set aside, reserving about 2 tbsp of fat in the pan.
Next, saute the onion and garlic for 5 minutes or until translucent. Add the riced cauliflower and saute for 5-7 minutes or until softened
Add back in the ground beef as well as the broth, tomato sauce, cabbage, salt, and pepper. Stir well to combine and coat the cabbage for a few minutes.
Place the lid over the dutch oven and simmer on low for 15 minutes, stirring every 5 minutes or so to allow the cabbage to soften.
Remove the lid and stir well, topping with parsley to serve.
