A great vegetarian comfort food that also makes a great holiday dish. This recipe is a favorite among many that have discovered the deliciously tasting Worthington FriChik. You can also use real chicken, mayonnaise, milk and even add some cheese if you're not vegetarian. Before becoming vegetarian I made a casserole very similar to this one regularly. I got this recipe from a good friend that got it from another friend's cookbook. Worthington FriChik has egg white in the ingredients and there is cream in the mushroom soup, so its not vegan. I've been trying to use as little dairy as possible so I use soy milk and vegenaise (the yummiest soy mayonnaise).
