Preheat large Dutch oven or pot on medium heat and swirl oil to coat. Add onion and saute for 3 minutes, stirring occasionally.
Add ground turkey and cook for 5 minutes, breaking into pieces and stirring with spatula.
Add pasta, stock, salt and pepper; stir and level with spatula. Then cover and cook on low heat for 10-12 minutes, checking after 10 minutes. Brown rice pasta and any gluten free pasta cooks faster than wheat.
When pasta is al dente (not too soft, so it doesn't become a mush), turn off heat and add broccoli, tomato, garlic and red pepper flakes. Stir, cover and let stand for 5 minutes.
Add parsley and Parmesan cheese and gently stir. Serve hot.
