Beef and green bean stir fry (sounds weird, but very good)
 

A recipe I found awhile back that makes a fast and tasty meal; the ginger is optional, and using a little sesame oil in place of some of the vegetable oil adds an interesting flavor if you have it.

Ingredients
1 clove garlic, minced
Ginger, 1/2 inch piece, jullienned
1/4 teaspoon ground black pepper
1 teaspoon cornstarch
1 teaspoon vegetable oil
1 pound sirloin tips, thinly sliced
3 tablespoons vegetable oil
1/2 onion, thinly sliced
2 cups fresh green beans, washed and trimmed
1/4 cup chicken broth
1 teaspoon soy sauce


Directions
1In a large mixing bowl, combine garlic, black pepper,
cornstarch, ginger, and 1 teaspoon vegetable oil. Add beef, and
mix well.
2In a large wok, heat 2 tablespoons oil over high heat
for one minute. Add meat and ginger; cook and stir for about 2
minutes, or until beef begins to brown. Transfer beef to
a large bowl, leaving as much ginger and broth from the beef as possible and set aside.
3Heat remaining 1 tablespoon oil in the wok used for the beef. Add onion; cook
and stir until tender. Mix in green beans, and add
broth. Cover, and reduce heat to medium. Simmer for 4 to
5 minutes, or until beans are tender crisp. Stir in soy
sauce and beef. Cook, stirring constantly, for 1 or 2
minutes, or until heated through.

Serve over rice.
