I love them too. It's popular as a street food in Thailand (called 'miang kum') but I have only found them in a few Thai restaurants around the U.S. You can just dice up some fresh ginger, cashews or peanuts, toasted coconut, bits of lime with the rind, red onions, grated carrots, and cucumber and put whatever chutney or sauce you like with it and roll it all up.

The wonderful thing about collard rolls is that you can put anything in them. Here is the basic recipe I use http://www.gojee.com/food...
