I want to say no.....but I'm Arab and we like to GRUB

eta: wait, what time of day is it and how many of the 36 are adults?

I don't think you have enough. Depending on how the heros are sliced you may get 48 pieces- 3" slices. If people come hungry they may want two slices or even come back for a third slice.

@mrsjazz: it's dinner time, so I would order more sandwiches. Not the Eggplant hero, because kids may not like that and you want to have something that everyone can grab if they come back for seconds.
The good thing is: it is all cold and it is all the type of food you can box up and bring home to finish up. So, I'd err on the side of caution. Remember: half the fun of a party is the food + it is at that time of day that people need a full meal, if it were a brunch, that'd be different...
If you can;t do the sandwich, maybe some crackers & hummus dip? Some sort of filling side like that. You've already got your carbs and you've got salads covered.
