Cheesy Chicken Casserole

WARNING! This is extra extra cheesy!!! lol
This recipe came from a family friend and was orignally named "Sopa Chicken". We liked this recipe, but I think next time I'll use only half of the velveeta it called for.

1/2c celery, chopped
1 small onion, chopped
2T. oil
4 chicken breasts, boiled and cut up
1 can Rotel
1lb 1/2lb velveeta cheese
1 can cream of chicken
small flour tortillas
1/4lb cheddar cheese, shredded
*cooking spray

Preheat oven to 350 degrees. Spray a 9x13 casserole dish with cooking spray. In a skillet, saute onion and celery in oil.

Add Rotel, cream of chicken, velveeta, and chicken; heat until cheese is melted. Put a layer of tortillas in the casserole dish, then a layer of the chicken cheese mixture, then another layer of tortillas, then a last layer of chicken cheese mixture.

Top with shredded cheddar cheese. Bake for 30 minutes.

Cheesy deliciousness.

You might want to toast the tortillas (in a skillet with a little bit of oil) before putting them in the dish. I think it tastes better with crunchier tortillas.
