This recipe came from the cookbook "Take Five for Every Occasion". All of the recipes require only 5 ingredients and are easy to make. My oldest daughter, Amy, doesn't like chicken, but she will eat this. It has a punch to it from the Ro-tel tomatoes. I've never timed the recipe so 30 minutes is prep. time which is cooking the vermicelli and cooking and chopping the chicken after it cools. The process cheese can be cubed or shredded. I've always cubed mine, because Velveeta will stick to any tool used to shred it.
