It may be tasty, but there is nothing vegan about this recipe, even if you are using "veggie hamburger."
Neither cheese, nor cream of anything soup is vegan, as vegans do not eat any animal by-products: cheese and cream included.
I am always looking for vegetarian main dish recipes that are easy and good. This one is a keeper! I didn't have cream of celery soup, so used two cream of mushroom. I also used mozzarella cheese. I will be making this often! Thanks.
