Have you tried Nutritional Yeast? It’s not the leavening yeast that makes bread rise (nutritional yeast contains no live enzymes) and it’s not Brewer’s yeast either. It is a condiment/ingredient and dietary supplement (rich in minerals, B vitamins - particularly B12 - and protein) that has a nutty, slightly sweet flavor that many describe as cheese-like. It’s animal-free, dairy-free, sugar-free and Kosher.
You can use it to add flavor and nutritional value in recipes for sauces and gravies; mix it into scrambled eggs or tofu; keep it in a shaker to sprinkle on salads, popcorn, pasta, baked potatoes or sandwich fillings; add it to casseroles or beans; etc.
There are a number of brands, but I recommend only Red Star Vegetarian Support Formula Nutritional Yeast. Its manufacturing process guarantees it is the only proven, reliable vegan source of Vitamin B12. You can find the yeast at many health food stores in flaked or powdered form – both have a yellow coloring. Store it in a cool, dry place or refrigerate it. It keeps indefinitely.
