I work in a physical therapy clinic and we are hosting a 'girls night out party' I need to make two appetizers to have for about 20-40 women. We have only a microwave (and a pretty weak one to boot) so they need to be cold or room temp. I am going to make a fall crostini with homemade ricotta, butternut squash, mushrooms,apples, and carmelized onions. I need one more appetizer. Any thoughts?
