From Publix Apron Recipes. Very simple and tasty!
1/2 pounds boneless chicken cutlets
1/2 teaspoon dried thyme leaves
1 tablespoon extra-virgin olive oil
1/2 cup pre-diced onions
4 ounces pre-sliced baby portabella mushrooms
1/4 cup Marsala wine
1/2 cup reduced-sodium chicken broth
1 (.75-ounce) packet mushroom gravy mix
Preheat large sauté pan on medium-high 2–3 minutes. Sprinkle both sides of chicken with thyme. Wash hands. Place oil in pan; swirl to coat. Add onions and mushrooms; cook 3–4 minutes or until tender. Move onions and mushrooms to outer edge of pan. Place chicken in center of pan (wash hands); cook 2–3 minutes on each side until browned. Stir in wine, then add remaining ingredients. Stir until well blended. Reduce heat to low and simmer 6–8 minutes until sauce thickens and internal temperature of chicken reaches 165°F. Use a meat thermometer to accurately ensure doneness.
