In a large skillet pan over medium-high heat, cook ground turkey, onion, carrots, garlic, salt and pepper until meat is no longer pink and carrots are crisp tender (about 5-7 minutes). Break up the meat into small crumbles as you cook it. Drain if needed.
Sprinkle the flour over the meat and cook for about 1 minute, stirring constantly. Stir in the tomato paste, beef broth, Worcestershire sauce, oregano, and thyme. Stir to combine and let it come to a boil. Once boiling, reduce heat to medium-low and let simmer for 15 minutes or until thickened.
Add frozen peas and corn, stir to combine and let simmer for 5 minutes to heat through.
Open up a baked potato and gently squeeze the ends together to form a bowl shape and to loosen up the potato in the middle. Sprinkle some cheese over the potato, then top with desired amount of shepherd's pie filling, and then top with additional cheese. Serve!
