I need some input for an office party. We have 10 people. I was thinking of order 1/2 tray of baked ziti and 1/2 tray chicken parm but I want to make sure I have enough food. They list 1/2 feeding 5-6 people. Last year they up sold me on a sandwich platter that I think would've fed more than double the crowd I had, so much was wasted and thrown out.
