First off this would be better off in the general discussion area...Now to become a ROM chef there are quite a few tutorials on this but first you will need a kitchen...Since you have a Pro I am giving you link to the release of PPCKichen's 20931 build found here

Once you have used this Kitchen and have the hang of it then there are others out there that are a little more packed with apps and other goodies...
Then once you are/become a little more advanced here is a great compilation of tutorials that will take you to the next level of being a master chef
