I did a search for a recipe containing chicken breast, mushrooms and fresh baby leaf spinach and I found this delicious and simple recipe on AllRecipes.com. It is very easy to put together and I found it to be quite tasty. I hope you will enjoy it!
Preheat oven to 350°F.
Place the chicken breast halves on a baking sheet and bake 20-30 minutes, or until no longer pink and juices run clear.
Remove from oven and set aside.
Increase oven temperature to 400°F.
Melt butter in medium saucepan over medium heat.
Stirring constantly, mix in the garlic, lemon juice, cream of mushroom soup, Italian seasoning, half-and-half, and Parmesan cheese.
Arrange spinach over the bottom of a 9x9-inch baking dish sprayed lightly with cooking spray.
Cover the spinach with mushrooms.
Pour half the sauce mixture over the mushrooms.
Arrange chicken breasts in the dish over the mushrooms then cover with remaining sauce.
Sprinkle with bacon bits, then top with mozzarella cheese.
Bake for 20-25 minutes in 400°F oven until bubbly and lightly browned.
