Honestly - from what I'm told the point of the meatless burgers is that it takes less land and resources to make a plant burger than it does to raise a cow. So the point of the meatless burgers isn't necessarily that they are less calories or more healthy (I have no idea if the amount of fat, etc., bears that out). The biggest point of making meatless burgers is that they are environmentally friendly.
As for me and my house - I prefer to eat the cow.
