Bring a pot of water to boil for pasta. When it comes to a boil, add pasta and salt to season the cooking water. Cook pasta 6 minutes to al dente.
While water comes to a boil and pasta cooks, heat a deep skillet over medium high heat. Add extra-virgin olive oil then butter then ground meat. Break up meat and crumble, 2 to 3 minutes. Add garlic, onions, red bell peppers and seasonings to the turkey. Cook 5 or 6 minutes then add chicken stock and sour cream to the pan. Bring to a bubble and reduce heat to low. Add cooked pasta and stir. Let pasta absorb some sauce, a minute or so. Adjust seasonings and serve. Garnish the prepared dish with chopped parsley and dill.
