2 pounds frozen boneless skinless chicken breasts
1 (16-ounce) package spaghetti
1 (10-ounce) can Ro*Tel Tomatoes
2 (10.5-ounce) cans cream of mushroom soup
1 (16-ounce) package Velveeta cheese
4 ounces cream cheese
1 teaspoon garlic powder
1 teaspoon onion powder
1 cup shredded sharp cheddar cheese
Place the chicken in a large pot and just cover with water. Cook over medium-low heat until cooked through. Try not to boil the chicken as it can make it tough. Allow to cool enough to handle, then shred using two forks.
Preheat the oven to 350°F. Lightly grease a 13x9-inch baking dish with nonstick cooking spray.
Cook the pasta according to the package
