Here is what they look like when you buy them:
To cook them you can either fry them in oil or microwave them. Neither method takes very long. I have not tried frying, but online it said about 2 or 3 minutes. Microwaving takes roughly 30 seconds. They are done when they have puffed.

They are now about the size of a potato chip. It is really fun to watch them grow. If you overcook them in the microwave they will burn. I found that out the hard way. :) They taste a lot like pork rinds and have the same texture. So if you like pork rinds you will like these. They are very dry so having some salsa or Tabasco sauce to dip them in is great. Also suggested online is lime and chili, which is what I will be trying next.
If you see some at your local store pick some up for a great treat!
