Kale? You have got to be kidding me. Build a restaurant on Rabbit food?
If there were a demand for that crap, Ray Kroc would have added it to the menu back in the 50’s. People go to restaurants because they want to feel satisfied when they leave. The reason rabbits eat that stuff is because no one else will and rabbits can’t kill anything. Rabbits eat it so they can feed Coyotes. If you want to be the prey of a pack of Coyotes, then load up on Kale. They’ll smell you coming and surround you on your morning jog.
