Place all vegetables in a food processor and process until vegetables are made into a paste. Set aside.
In a large, high sided skillet, heat 1 T olive oil over medium high head and add turkey. Cook turkey until cooked through, breaking up and stirring occasionally. Add processed vegetables and season with salt, pepper and thyme. Stir veggie mixture and turkey together and then cook, 5 minutes.
Add broth, worcestershire sauce and macaroni. Bring to a boil, cover and reduce heat to medium/low. Continue to cook, stirring occasionally, until pasta is cooked through (about 10 min).
In a small bowl whisk together ¼ C broth and flour; stir into meat mixture then stir in yogurt. Simmer 3-4 more minutes, stirring often to make sure everything is combined.
Garnish with parsley if desired.
