The only people who can check do not usually read these sentence discussions, I think :)
They're probably kept busy as a one-legged man in an ass-kicking contest just handling all the reports that people send in, and any time spent perusing sentences would take away from that.
So please use that way to contact them about missing alternatives rather than posting here :)
(When you are told that an alternative is wrong and you're pretty sure it's correct, then click the button "Report a problem" and choose "My translation should be accepted". That will make your suggested translation show up in the maintainers' interface by the sentence for them to accept or reject it.)
I think Duolingo needs to start awarding people for reporting stuff! I am not saying give them a pokémon, but give them something. Something that shows on their profiles. That should help a lot.
Why is it not a definite conjugation used here if the translation suggests "the dishes"?
