The Unstoppable Force
This is one of the best cooking guides. It's very economical even post-nerfs. Only tough part is getting the karma mats but that's the way of cooking no matter what route you take.
I usually nab 20 quick levels on all my characters via max cooking. Basically all of them are max level chefs + 2 other disciplines. Rarely spent over 1.5 gold unless I am feeling lazy.
Crafting is so easy in this game. Can max all of the disciplines out in like a day for close to 80 'free' levels. Though I usually only do like 30 or so in a day.
