Let the folded frozen puff pastry sheets thaw on a cutting board for 20 minutes. Cut straight into the folded puff pastry, cutting it into three equal squares.
2 sheets frozen puff pastry
Transfer the puff pastry squares to a baking sheet and prick all over the tops with the tines of a fork.
Bake at 400° for 12-14 minutes, just until puffed up and golden brown & crispy on the outside. Remove from the oven and set aside.
Set a large skillet over medium heat and melt the butter. Once melted stir in the onion and cook until softened, about 3-4 minutes. Add the celery, carrot, and mushrooms to the skillet and saute another 4 minutes, then transfer the mixture to a waiting plate. Set aside.
2 tbsp butter, 1 small yellow onion, 2 stalks celery, 2-3 large carrots, 8 oz sliced baby bella mushrooms
Add the broth to the skillet and using a sturdy spoon deglaze the pan, scraping up any stuck on browned bits. Bring the broth to a simmer over medium low heat.
2 cup chicken broth
Whisk the cornstarch into the half and half together, then pour the mixture into the simmering broth stirring to evenly combined. Continue simmering, stirring occasionally, just until thickened enough to coat the back of a spoon. Whisk in the seasonings.
1 cup half and half, 3 tbsp cornstarch, 1/2 tsp Italian seasoning, salt & pepper
Return the veggie mixture back to the skillet along with the turkey and peas and stir to combine. Simmer over medium low heat for 5 minutes, just until hot and bubbly.
