The Jalapeno Heat, Vinegar Splash, and Classic Sea Salt are all vegan. The Vinegar is particularly good. These are just puffed potato starch in a regular snack chip bag so don't get too excited, but they are nice and crispy. 1.5 grams of fat doesn't seem like a lot, but you'll feel the ooze on your fingers.
Here are the nutritional facts. http://gourmetbasics.com/page001.html
You'll see for every 110 calories 10 (Classic Sea Salt) to 15 (Vin&Jala) are from fat.
10 fat calories out of 110 calories per serving = 9% fat. (Only 1 serving per container, too!)
15 fat calories out of 110 calories per serving = 13.6% fat
Not terrible considering the butter popcorn alternatives. I wouldn't stock up on these for lunch boxes or anything, but a fun snack at the movies its not a bad deal. The sodium is a little high, but drink some of that expensive bottled water (sneak in your own).
