Melt the coconut oil in a large skillet over medium-high heat. Add onion and garlic; sauté for 3 to 4 minutes or until onion is tender.
Next, add mushrooms; cook for 3 minutes or until softened. Add lean ground beef; cook, breaking up with a wooden spoon, until no longer pink. Finally, add next 6 ingredients (carrots through black pepper); blend well.
