Our DIY office party brings in 40-60 people, crammed into an apartment, mostly standing. Over the years, we've done tamales, spanakopita, and pita with Middle Eastern spreads. Need some new ideas. Should be a) hand-held, b) not too messy (disqualifies tacos and tostadas, I'm afraid), c) can be eaten luke-warm or room temp (disqualifies deep fried things), and d) have a vegetarian version. This could be the year of the Jamaican patty or baked empanada, if I could find a good one. Or moderately-sized burritos, if anyone makes these other than Taco Bell or your local supermarket freezer section. Any suggestions? Brooklyn would be preferable. Queens (not too far east) or Manhattan (not too far north) are doable.
