Recipes for Bean Sprouts
Mung bean sprout or soy bean sprout?
There are tons of recipes for bean sprout. Stir fry is definitely the most common one. I would use soy sauce instead of oyster sauce. However, the Korean Bimbimbap is definitely one which take advantage of bean sprout without stir fry. A wonderful dish.
I love the Korean style bean sprout side dish. It is easy to make, and can be made with either mung bean or soybean sprouts. I like the methods outlined here:
Chinese places often make fairly similar cold side dishes with bean sprouts.
I often use soybean sprouts to make a simple vegetarian stock too (along with some kelp).
Besides the obvious stir fry, I love them in Spring Rolls: http://vegetarian.about.com/od/maindishentreerecipes/r/ThaiSpringRolls.htm

Add them to an Asian-inspired salad.
I do a good old plain version by stir-frying them in sesame oil, with some minced garlic and ginger, and finishing w/ a dash of soy sauce. Nothing fancy, but so good. Also nice w/ thinly sliced celery added, or anything else crunchy that you like: cabbage, water chestnuts, julienned bamboo shoots. Good stuff. I also add them to a Japanese cucumber salad, combining them with thinly-sliced cukes and onions (tamed) and more of that celery, and making a dressing from seasoned rice wine vinegar and a bit of sesame oil and salt, and just letting it sulk in it's own marinade for a bit.
