This was delicious and you could easily change it to suit your family's tastes (a couple of my kids grumbled at the tomatoes and spinach!). This would be wonderful with ham, broccoli, mushrooms, sun-dried tomatoes... so much! It completely fills a 9x13 baking dish, so if you have a smaller family you could divide it into two 8x8 pans.
1 lb rotini pasta, cooked a little less than al dente
2 lbs chicken breast, cubed and cooked
2 cans condensed cheddar cheese soup
1/2 cup real bacon pieces
1 cup milk
1 cup mayonnaise
4 medium tomatoes, seeded and chopped
3 cups fresh baby spinach, chopped
2 cups colby-jack cheese
Preheat the oven to 375. In a large bowl, combine all of the ingredients except the shredded cheese. Pour into a 9x13 greased baking dish. Sprinkle with shredded cheese. Bake for 35-40 minutes.
To freeze: Once in baking dish freeze. Thaw, or mostly thaw, before following baking instructions above. You will probably have to add 15-20 minutes to baking time.
