I'm generally againts GMO, but I'm gonna make an exception here. Meat in Tundra!
I did some math to compare it with rice, if you're aiming for fine meals like I do:
on 100% soil, they perform ~ 1:1,4 (rice:tofu)
in hydroponics, they perform ~ 1:1,6 (rice:tofu)
Seems balanced to me. Calculations were done based on game data.
