I have been asked to cater a cocktail party for 150 women. The budget is limited - $10/person total. I will not be providing plates, utensils, napkings just food. I'm looking for suggestions for finger foods/appetizers that are inexpensive to keep cost low while still having a small profit. Also, this is the first time i will be doing an event this large - suggestions on best way to transport/keep warm foods warm, etc? Thanks in advance!
