Preheat oven to 375°.
Melt butter in a saucepan and whisk in the flour. Cook 1 to 2 minutes.
Slowly whisk in chicken broth until smooth. Add salsa verde, heavy cream, sour cream, granulated garlic, ground cumin, salt and pepper.
Bring to a simmer and cook until thickened. Remove from heat and stir in 1/2 cup cheddar cheese until melted.
Pour one third of the sauce into the bottom of a greased 9 x 13 baking pan.
In a large bowl, mix together softened cream cheese, shredded cheddar, diced jalapeno, granulated garlic, salt and pepper until combined. Stir in chopped turkey.
Spoon turkey filling onto flour tortillas and roll up, tuck in the ends to fit into the pan if needed.
Place each filled tortillas into the pan over the sauce.
Pour remaining sauce over the filled tortillas.
Bake uncovered for 30- 35 minutes until sauce is bubbly.
Remove from oven and rest about 5-10 minutes.
Spoon more salsa verde over the enchiladas if desired and garnish with cilantro.
Serve with sour cream and pico de gallo.
