Monterey Chicken Spaghetti Casserole: My whole family loved this simple chicken casserole! Even our pickiest eaters loved it! You can add chicken, pasta, cream of chicken or sour cream to this dish. Also, you can add spinach, Monterey Jack Cheese and french fries. This makes a great freezer meal. This is our most requested meal.

This Monterey Chicken Spaghetti IS THE BEST! Spaghetti chicken with Monterey Jack cheese, spinach and French fried onions. Seriously delicious! This was delicious! This was just the right amount of spinach for me. You can double the amount if you prefer lots of spinach. A little bit of spinach can go a long way, according to me.
