This is so yummy. I was hesitant at first because of the soup ingredients, but I have made it many time since and everyone raves! I have used reduced fat soup and less cheese, and it is still great.
Cook pasta in a large pot of boiling salted water until al dente. Drain.
In a large bowl, mix together cream of mushroom soup, cream of chicken soup, chopped onions, cottage cheese, sour cream, poultry seasoning, oregano, basil, grated Parmesan cheese, and chicken. If desired, add olives.
In a 9x13 inch casserole dish, layer 3 lasagna noodles, half of the chicken sauce, grated Colby cheese, 3 lasagna noodles, remaining chicken sauce, 3 lasagna noodles, and finally grated mozzarella cheese. Cover with aluminum foil.
Bake in a preheated 350 degree F (175 degrees C) oven for 40 minutes. Remove foil, and continue baking for 10 minutes. Let stand 10 minutes before serving.
