Chicken Lasagna

Chicken Lasagna

1 (10 oz) box frozen chopped spinach
2 cups chopped cooked chicken
2 cups shredded cheddar cheese
1/3 cup fine chopped onion
1/4 - 1/2 tsp. nutmeg
1 Tbsp. cornstarch
1/2 tsp. salt
1/4 tsp. pepper
1 can cream of mushroom Soup
1 (8 oz) sour cream (or a little more)
1 jar sliced mushrooms
1/2 cup mayonnaise (or 2/3 cup)
1 cup grated fresh Parmesan cheese
Lasagna noodles

Cook noodles, drain and set aside (or use oven-ready noodles). Press spinach between paper towels to get all of the liquid out. Combine all ingredients (except noodles) in large bowl and stir well. In large casserole dish, layer noodles and chicken mixture repeatedly until all is used (3 or 4 thin layers). Sprinkle with more grated Parmesan. Bake 350 degrees for 55-60 minutes, until hot and bubbly.
