This Parmesan substitute has a salty flavor and the texture is just like the canned dairy version. I used this "cheese" in a creamy slaw salad dressing and it tasted great. The ingredients are nutritional yeast flakes, sea salt, and walnuts (recipe from the Go Dairy Free cookbook).
It was interesting to read up on nutritional yeast. I try to avoid yeast when possible, because I know that yeast overgrowth is very common and can cause major fatigue. (This is another good reason to avoid sugar, because yeast thrives on sugar.) But nutritional yeast is different from baker's yeast and brewer's yeast because it has essentially been "deactivated" in processing, and therefore cannot grow or cause candida. In addition, nutritional yeast has tons of vitamins and minerals!

other things like cheesy casseroles or sprinkled over spaghetti with
