Yeah, the cal content isn't much different. It's for people that don't want to eat meat. But, it's still cooked on same grill! Strict vegans stay away! Also, it's soy based.
It's not just if you're vegetarian, it's that large-scale meat production is unsustainable if we're trying to put even a dent in climate change. Our meat makes a lot of pollution before it gets to our plate, so if Impossible and Beyond can make burgers that are just as substantial energy wise while tasting about the same, it's just a more responsible thing to do.
