My Best Friend's Chicken Enchiladas

This is my very good friend's go-to recipe.  I made it for the first time a couple of weeks ago and was so excited by how much it made!!  Plus, it tastes pretty good ; )

1 3lb bag skinless boneless chicken breasts
2 8 oz cream cheese
3/4 jar of your favorite salsa
1 28 oz can enchilada sauce
3 cups shredded cheddar cheese (or a combination of Monterey jack, etc.)
1 can olives
2 10 count packages of tortillas

Boil and shred the chicken.  Melt the cream cheese and salsa together, stir in shredded chicken.  Fill tortillas and roll (don't close the ends).  Spray 2 9x13s and fill with 10 each tortillas.  Pour enchilada sauce over top, cover with cheese and olives.  Bake at 350 for 30 minutes.
