Nissin UFO Yakisoba is an old classic of Japanese instant noodles that simulates having stir-fried noodles. The original UFO comes in a pie-pan shaped package that resembles the classic saucer-shaped UFO, but these days there are bigger packages of these noodles in square trays. These noodles actually replicate the experience of fried noodles pretty good once the sauce is mixed in because the noodles themselves are deep-fried like most instant noodles. The people that thought of doing this were pretty inventive and this is a popular type of instant noodle in Japan. This isn't an unusual instant noodle and is very common, like Cup Noodle.
