To the same skillet, add the dry white wine and simmer for a few minutes, until the wine is reduced by at least half, scraping the bottom of the skillet with a wooden spoon to release any browned bits from cooking the chicken.
Add butter, and once melted, add sun-dried tomatoes and garlic. Cook for about 30 seconds or so, until fragrant.
Sprinkle in the all purpose flour and whisk to combine.
Pour in the chicken broth, whisking as you pour, then pour in the heavy cream.
Add the last 1 tsp of dried Italian seasoning, paprika, onion powder, garlic powder, and parmesan cheese. Whisk to combine well.
Stir and simmer a bit, until thickened enough to coat the back of a wooden spoon.
