Ingredients

1 lb cubed filet mignon
Marinade
3 garlic cloves, minced
1/2 teaspoon black pepper
1 teaspoon sugar
1 tablespoon oyster sauce
1 teaspoon dark soy sauce (thick)
Dressing
1 shallot, thinly sliced
1 1/2 teaspoons sugar
1 clove finely minced garlic
1 pinch salt
1 pinch black pepper
1 1/2 tablespoons unseasoned rice vinegar
2 tablespoons water
4 cups romaine lettuce, salad
1 dash sesame oil

Preparation

Trim excess fat from Filet Mignon and then cut each into 3/4-inch cubes. In a bowl, combine the pepper, sugar, garlic, & oyster sauce. Add the beef and toss well to coat. Set aside to marinate for 20 minutes or up to 2 hours.
For the dressing, In large mixing bowl, combine the sugar, garlic, salt, pepper, vinegar and water. Stir to dissolve the sugar. Add the shallot and sesame oil. Put the romaine or watercress salad on top but hold off on tossing.
Heat the oil in a wok or large skillet over high heat. Add the cube Filet Mignon and spread it out in one layer. Cook in batches, if necessary. Let the beef sear for about 1 minute, before shaking the wok or skillet to sear another side. Cook for another 30 seconds or so and shake. Cook the beef this way for about 4 minutes total, until nicely browned and medium rare. Add cubed bell peppers, white onions, and mushrooms. Finally, add the dark soy sauce to enhance the flavor & color of the shaking Filet Mignon.
In between shakes, toss the romaine or watercress salad and transfer onto a platter or serving dish. When the beef is done, pile the beef on top of the romaine or watercress salad and serve immediately with lots of rice.
