Actually there is a new ‘veggie product’ called ‘impossible burger that they claim really does taste just like hamburger- and has similar texture as well

Seen a lot of reviews on it after it was featured on The show “The Wallburgers” - Even they couldn’t tell the difference supposedly-
Someone on Fr said they tried it and yep- it was great-
No one ever tried to make meat taste like vegetables...
