Let the sauce simmer for about 15 minutes, or until it thickens enough to coat the back of a spoon. Taste the sauce and add salt as needed. At this point, add the beef back into the pan. Add the green onions, stir, cover, and let the beef cook over medium heat for 3 minutes, or until the green onions are wilted. Turn off heat and serve with your choice of cauliflower rice
or white rice!
