Step 1: Begin by gently pounding the chicken breasts to an even thickness, about ½ inch thick. Season both sides of the chicken with salt and pepper.
Step 2: In a shallow dish, combine the flour, salt, and dried oregano. Dredge each chicken breast in the flour mixture, making sure to shake off any excess flour.
Step 3: In a large skillet, melt 2 tablespoons of butter over medium-high heat. Add the dredged chicken breasts to the skillet and sauté for 4-5 minutes per side, or until golden brown and cooked through. Remove the chicken from the skillet and set aside.
Step 4: In the same skillet, add the remaining tablespoon of butter. Once melted, add the minced garlic and sliced mushrooms. Sauté for about 4-5 minutes, or until the mushrooms are tender.
Step 5: Deglaze the skillet by adding the Marsala vinegar and scraping the bottom of the pan. Add the chicken broth and bring to a gentle simmer. Allow the sauce to reduce for about 5-7 minutes, or until it thickens slightly.
Step 6: Return the cooked chicken to the skillet, nestling it into the mushroom sauce. Spoon some of the sauce over the chicken to coat. Sprinkle the shredded mozzarella cheese on top.
Step 7: Reduce the heat to low, cover the skillet, and let the cheese melt for about 5 minutes.
Step 8: Garnish the Chicken Lombardy with the sliced green onions and serve immediately.
