Nong Shim Onion Flavored Rings are a Korean product available in many Asian markets. They have a much lighter and delicate texture than Funyuns - puffier and airy. The flavor is lighter and a bit "sweeter" than Funyuns, but still deliciously oniony.
The label says that they contain "bacon powder," which sounds totally awesome but which, in fact, imparts very little flavor of it's own.
Still, they're quite tasty, not too salty for a chip-like snack, and they don't leave your fingers greasy or coated with some strangely-colored powder. Good stuff.
