How much pizza gets eaten when you throw a birthday party during lunch? I was thinking 1.5 slices per kid (2-6yo) then probably 2-3 per adult?

We will also have snacks like veggie tray, fruit kebobs, etc. Will probably have a sandwich tray and pasta salad for variety.

I don't want to not have enough food, but the party won't be at home, so I don't want a ton of leftovers either!

Just trying to set a loose but realistic food budget.

Thanks!
