Step One: Prepare the Chicken
Pound chicken breasts with a meat mallet until about 1/3-in thick. Sprinkle with salt and pepper.
Step Two: Cook the Chicken
Heat the olive oil in a large nonstick skillet over medium heat. Pour whole-wheat flour on a medium plate and fully coat the chicken, shaking off any excess. Place chicken in the skillet and fry until golden brown, approx. 4-5 minutes per side. Transfer chicken to large plate, or serving dish, and cover to keep warm.
Step Three: Make the Sauce
Add the chicken broth and sun-dried tomatoes to the same skillet while stirring frequently for approx. 1 minute. Then add the mushrooms and cook until the mushrooms are soft, approx. 4-5 minutes. Add salt and pepper to taste. Add the wine and bring all ingredients to a simmer. Finally add the butter and continue stirring until melted (approx. 1 minute).
Step Four: Serve
Spoon the sauce over the warm chicken and serve with your choice of greens. Garnish with chopped parsley if desired!
