[MIRROR] Fixes custom pizzas magically generating dairy products and vegetables. (#26722)

* Fixes custom pizzas magically generating dairy products and vegetables. (#81683)

## About The Pull Request
This fix is for pizzabreads being made into a custom pizza that
magically become dairy and vegetable based foods, even if you added
neither.
## Why It's Good For The Game
People with dairy allergies and those that may not like vegetables, I
guess?

(This one has vegetables, 'cause I added tofu)
