That’s partially the point I intended but failed to make. We can grow lentils easily, then just eat them! It’s insanely efficient.
Feeding crops to cows is bizarrely wasteful when you look at the big picture. Especially once you look at the subsidies that make meat affordable, the water usage we can no longer afford, the pathogens animal agriculture generates, etc. It seems completely untenable from my perspective. Which is strange to consider at times, because I was once a huge proponent of eating meat.
