Heat oil in a pot over medium heat. Add the ground beef and break it apart with a spoon. Cook until browned, 8 to 10 minutes.

Add the bone broth, rice, spinach, tomatoes and pinch of salt and pepper. Stir to combine. Bring to a boil, then reduce heat to low, cover, and cook for 12-15 minutes, or until the rice is fully cooked. Serve.
