Combine 1 tablespoon of flour, the smoked paprika, garlic powder, salt and pepper in a bowl. Add the cut up chicken to the mixture and toss until all the pieces are coated.

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Swirl to coat the bottom and then add in thee chicken. Spread it out into a single layer and let it cook for 3-4 minutes before moving it. When the chicken is cooked through, remove it from the skillet and onto a plate.

Lower the heat to medium and add the remaining tablespoon of oil to the skillet and pour in the onion and mushrooms. Sauté for 3-4 minutes and then add in the garlic, thyme, salt and pepper. Cook for another minute.

Sprinkle the remaining tablespoon of flour on top of the vegetables and stir until you can no longer see any streaks of flour. Pour in the chicken broth, dijon, and sherry vinegar. Stir until combined and the sauce thickens enough to coat the back of a spoon.

Remove the skillet from the heat and vigorously stir in the Greek yogurt until it's fully incorporated. Taste for seasoning and serve on top of egg noodles. Garnish with chopped flat leaf parsley if desired.
