Chicken dorito casserole

How do I figure out the vitamins % for this recipe. I think you could use baked doritos and low fat soup to make it healthier but I found the nutrition values with the regular kind.

1 bag Doritos-Crushed
1 can cream of chicken
1 can cream of mushroom
1 can rotel
1 pound sliced chicken(I use the frozen fajita meat)
1 cup cheese

Place the doritos in the bottom of a 9X13 pan, mix the soups and rotel and layer on the doritos, place a layer of chicken and top with grated cheese Bake at 350 for 30 mins.

Not the greatest in the world for you but not too bad calorie wise and kills that mexican food craving!
