Do you guys have any ideas for some low calorie fillings I can make to use
in stuffed tomatoes?

I saw Alton Brown making some mushroom stuffed tomatoes on Food Network and
I didn't look up how many calories that was because the different kind of
mushrooms he was using were too expensive.

I'm thinking a little cous cous would be good, and some onion, but what
else?
