Instructions: In a 2-quart saucepan, simmer chicken breasts with celery, onion, thyme, salt, and pepper until tender, about 25 minutes. Remove chicken and let cool; cut in bite-size pieces or shred. Reserve 3/4 cup of broth. Discard remaining broth or freeze to use in another recipe. Break lasagna noodles in half; boil for about 5 to 8 minutes, until just a little flexible. Drain and rinse with cold water for easier handling. In a medium bowl, combine soup, tomatoes, gravy mix, and reserved broth. In a 3 1/2 to 4-quart crockpot, pour in 3/4 cup of the soup mixture. Place 4 to 6 lasagna noodle halves on top of the soup mixture. Add 1/3 of the spinach, 1/3 of the chicken, 1/3 of the mushrooms, and 1/2 cup of shredded cheese. Pour another 3/4 cup soup mixture over all. Repeat layers 2 more times, ending with remaining soup mixture. Cover and cook on low for 4 to 5 hours. If cooked too long, the noodles might become mushy, so check after about 4 1/2 hours.

Susan Says: This is similar to Chicken Spaghetti in ingredients and flavor. Very tasty!
