A lady named Kirsten brought this dish. She's one of the best chefs this side of the Pecos. Her family runs a GF store in Boise, and this is a link to their web page.
Anyway, here's the GF chicken lasagna you'll never forget:
Chicken Lasagna Recipe
1 cooked, boned chicken, diced
1 (8oz.) pkg. cream cheese
2 cans or 3 cups gf cream of condensed chicken soup
2/3 cup milk
1 pt. sour cream
1 tsp. salt
1 tsp. poultry seasoning
1 (10 oz.) pkg. gf lasagna noodles cooked al dente
1/2 lb. shredded Mozzarella
bread crumbs (ample)- or chex cereal blended finely
Combine chicken, cream cheese, cream of chicken soup, milk, sour cream, salt, and poultry seasoning in a saucepan and stir over low-medium heat until well blended and cream cheese is melted. Pour a small amount of this sauce in the bottom of a 9x13 pan. Layer with noodles, sauce, and cheese- repeat until all noodles, sauce, and cheese are gone. Hopefully cheese is your last layer- sprinkle with the bread crumbs and bake @350 30-45 minutes.
