Agano-neeeee?!I'd suuure like to eat some pudding....
* The delicious riceball was eaten by the Admiral later.
This is a parody reference to Japanese cooking shows. When cooks put food into the oven, then pull out a different dish that's already cooked to save time (i.e. "Here's one we made earlier"), elderly viewers complain that they're wasting food, so they have a notice saying that the finished meal was eaten and not wasted. Parodies of this, like in Sayonara Zetsubo Sensei, tend to poke fun at the idea that the staff HAS to eat excess food no matter how badly the cooks ruin it (cue Isokaze) or even throw it on the floor.
