That's on the way too! It's known as Precision fermentation, here in Germany we got dog food based on that technology approved not too long ago, and it's relatively cheap and available, so scaling up to human food shouldn't be too far away. (link to the dog food)

In the meantime, brands like Formo produce cream cheese based on Micro fermentation, which is the same process as Precision fermentation but the yeast/bacteria aren't genetically modified and only produce compounds the would produce normally. In Formos case they're using the bacteria that are used in White Miso production.

I haven't really been vegan long enough to miss any animal products either, but I absolutely love food science and following what the industry cooks up haha
