Hi osirion, you have me intrigued now! I have to have a look at the ingredients listed on the box of cheese to see what differs, I will let you know if I find anything different!
Some Subways sell the pizza sub as part of their menu range, we are all allowed to sell what is called a local market option and if all the stores in a district territory agree, then it goes on the menu for that area. But all stores still have all the ingredients to make up a pizza sub and they should not refuse you if you ask them. With the veggi option, once again the veggie patty is a local option and I am afraid if the local market decides to stop selling it, then it will be taken off the menu. It may be worth asking for it though, if enough customers ask then they may put it back on again. I think it is a shame if they don't as we don't have many veggi options to offer. We will be happy to make up the pizza sub for you and we stock the veggy patty, if you are ever in the Bournemouth area!!
Hope that helps, sorry to hijack your question a bit silverdaler!!
Cheers Sue
