They are pasta durado, a Mexican snack food. Put a couple in the microwave on high--they will puff up like Cheetos. (Watch them--it is cool, and your kids will like it. Also watch them, because it is a nanosecond between all puffed up and burnt.)
They are very bland, so they need some chili and salt, or maybe salsa?
An alternate way to cook them is to deep fry them. The oil must be hot--375 or so.
