Just got back from Barbados with a snack called "Tasty Channa". It looks like some sort of fried bean or pea, and was packed in a small plastic juice bottle. There were a whole bunch of brands, the one we got was by "S. Anthony" of Trinidad. the ingredients are channa, vegetable oil, salt, and pepper.
I love this stuff and would love to learn more, where to buy it in the US, or how to make it myself.
