Make meatball soup with turkey meatballs for an excellent supper shortcut.
In pot, cook mushrooms, onion and bell pepper in oil over medium-high, stirring occasionally, until softened, about 8 minutes. Add chicken stock, thawed Herbed Turkey Meatballs, garlic and thyme; bring to a boil. Simmer until flavors meld, about 12 minutes; season. Serve with rolls.
