If the patty looks like meat, if it bleeds like meat and if it sizzles like meat... the patty can somehow be a plant-based vegetarian burger, just like the cheeseburger above. It's called the Impossible Cheeseburger and it's completely made from plants.
You don't even have to eat a veggie burger to know that most veggie burgers suck. Even if you find a good veggie burger, it doesn't quite recreate the same visceral taste of eating a burger. The "meat" doesn't act like meat, it's either too bouncy or too tasteless or not bloody enough. A veggie burger can be good, sure, but it's never as a good as a burger.
But the bites still have the consistency of animal tissue. It isn't overly spongy like tofu, instead the meat granules cling together, as one would expect in a burger.
It is somewhere between beef and turkey, an assessment shared by Samir Kaul, a general partner at Khosla Ventures, a backer of Impossible Foods, who describes it as "better than a turkey burger." But what's wild about eating Impossible's burger, is that unmistakable, yet hard to define, sensation in your brain, that what you're eating isn't plant but animal tissue—something red-blooded that walked around before.
The secret for this plant-based burger is including heme, a molecule in hemoglobin that can be found in plants. The heme, according to the WSJ, "interacts with the plant's amino acids and nutrients during the cooking process, to unlock a bouquet of flavors."
All science aside, if it looks like what it does in the picture, I'd definitely eat it.
