While pasta is cooking, add butter to a large pot. Add frozen veggies and cook until thawed. Add flour and cook and stir for 1 – 2 minutes.
Stir in milk and bring to a boil. Cook until thickened and then add turkey, soup, sour cream, salt and pepper. Mix until well combined.
Drain pasta and add to sauce. Stir until well combined and then spoon into a greased 9x13 pan. Cover and place in the oven.
Top with cheese and cook for 25 – 30 minutes. Cook uncovered for an additional 10 – 15 minutes. Serve warm and enjoy!
Notes
STORE leftover pasta in an airtight container in the fridge for 2-4 days. Reheat individual servings in the microwave and larger servings in the oven or on the stovetop if need be.
