What the hell does Gregory eat???

Ok, so we know he doesn’t like pizza. And flavors. And he’s definitely not a fan of stuff that is “crusted, dusted and not to be trusted”. So what does this man eat every day? Just saltines and water?

It reminds me of Cpt. Holt from Brooklyn 99: “I have zero interest in food. If it were feasible, my diet would consist entirely of flavorless beige smoothies containing all the nutrients required by the human animal.”
