Preheat oven to 350.

Spray cooking dish with cooking spray, I like olive oil. Place uncooked chopped chicken into dish.

Sprinkle chicken with garlic salt then top with chopped asparagus (and mushrooms and onions if you like).

Cover evenly with the jar of prego white sauce and bake at 350 for 30 minutes.

Remove from oven and cover with onion topper then bake for 10 minutes more.

I served this with cornbread.
