Reply To: Eating "Dairy Out"– how common is this?

The cheese is a bigger issue than the pepperoni. The pepperoni is “reicha” or “vapor”, since you don’t know that there was pepperoni in the oven at the same time I don’t believe there is any bosar bichalav. However, there might be lard in the dough and there certainly is gvinas akum, which is ossur.
