Turkey Bolognese with Vegetables

Prepare spaghetti according to package directions; drain and keep warm.

Cook turkey in large saucepan over medium-high heat, stirring occasionally, until no longer pink; add tomato sauce, frozen vegetables, bouillon, sugar and oregano. Bring to a boil, stirring frequently, until bouillon is dissolved. Reduce heat to low; cook, stirring frequently, for 5 minutes or until turkey is cooked through and sauce is thickened. Serve with spaghetti topped with cheese.
