i personally use sweet potaoes/yams. i know they aren't exactly the same thing. but yams here in the U.S. are usually just called sweet potatoes, because i guess they are probably cheap so stores don't carry yams.
so i use sweet potatoes. but i do use oats too. i just buy the quaker oats "old fashioned" kind. nanners are ok too. but i just use those two primary sources for my carbs. and broccoli, i think i have a broccoli addiction by the way.
