If you are thinking about franchising, then you should really take a good look at your friends and your goals. The fees and procedures you would need on place to franchise are a giant task, and a very expensive process.
You also have to think about the possibility of failure. If something goes wrong the your friends could end up suing you or worse.
Packaging your products and selling them is also a challenge because of the different laws you will need to deal with. I looked into central dough production, and the health dept wanted me to add an additional $10,000 worth of equipment, from air curtains to automatic doors. It would not have been worth it.
You might be far better off to just help out your friend with some recipe advice. Pull a few dough recipes off PMQ, teach them how to make dough, and introduce them to your supplier for sauce options.
