Preheat the oven to 400F. Heat a tablespoon of oil in a large casserole dish or Dutch oven.
Add the onion and stir to coat in the oil. Cover the pot and cook the onion over very low heat for 10-15 minutes, stirring occasionally. The onion should be soft.
Stir in the minced garlic, chopped sun-dried tomatoes, salt and paprika. Sauté for a few minutes.
If the pan is getting a bit dry you can deglaze it with a splash of white wine (or chicken stock) but that is optional.
Add the orzo pasta and stir to toast in the oil and seasonings.
Stir in the diced turkey
Pour in the stock and bring to a simmer, scraping the bottom of the pan (orzo has a tendency to stick).
