[Question] Food Odor Dilemma

I hate school lunches, I'd rather go hungry. When I occasionally do bring in food from home and into the lunchroom I expect to be satisfied (because what else do I have to look forward to?). I'll bring in a sandwich from time to time, but the trend has gotten stale because my sandwiches fail to match against the $8 subs from my nearby deli. And unfortunately when I do bring in a homemade pasta salad, I'll get a couple glares due to the vinegar aroma. Does anyone have any lunch recipes that won't attract negative attention? Note: Due to dietary issues nothing too spicy or anything with a lot of cream, please and thank you.
