In a large skillet, heat olive oil over medium heat. Add the turkey, onion and garlic. Break the meat into small pieces as it is cooking. Cook the meat until it is brown, about 10 minutes, continuing to break the meat into smaller pieces if possible.
Add the chili powder, oregano, cocoa powder, cinnamon, nutmeg, cloves, cumin, salt, and pepper, stirring to combine, and cook until fragrant, about a minute.
Add the rice vinegar, brown sugar, tomato sauce, and chicken broth and stir again to mix all the ingredients together.
Reduce heat to low and simmer for 30 minutes. If desired, cook pasta and grate the cheddar cheese at this time.
Serve immediately over pasta, topped with cheese if desired, or just eat it plain.
