The real success in this area is the Impossible burger. It's made mostly from peas and soy, with heme added to produce the bloody meat texture. The heme is made in a fermentation process not much more complex than brewing. Impossible has no problems with volume production - they sell through Burger King and WalMart. Growth rate about 85%/year.
If they can get the end user price under control, they could displace a whole lot of beef consumption. At the current price point, it’s not nearly worth it on a taste or economic value comparison with 80% ground beef.
