Order Tag Setup for Add Product Group that goes with EVERY pizza: NOTE No prefixes needed here unless you want to use Extra for extra or Double. I can show you how to set that up.
This is how to set this up and map it correctly. You can expand on this to how many pizzas you want. and ingrediants you want… etc.
The important part for you is to pay attention to mapping portions of this tutorial thats where you specify what shows up on each pizza.
