Preheat oven to 400 degrees F.
Wash the sweet potatoes and pat them to dry, then piece all over using a fork. Bake them for about 50 to 55 minutes until fork tender.
Cook the ground turkey with a teaspoon of salt in a large non-stick pan over medium high heat for about 5 minutes (break up the meat while cooking).
Lower the heat, push the ground turkey to the side and add the oil, onion, celery, garlic, and tomato paste. Let them cook for about 5 minutes before mixing.
Add the peas, carrots, mushrooms, Worcestershire sauce, thyme and mix well to combine.
Mix the beef broth with flour in a small bowl before adding to the pan. Cover the pan and let it simmer on low for about 5 minutes until it reduces and the flavors blend together.
Once the potatoes are done cooking, slice them open and fill them with enough turkey mixture. Enjoy while hot!
