I don't have a recipe that I personally have tried, but here is a recipe the might be what you are looking for. If not hang in there, I am sure someone here at DC will have a recipe for you. I got the recipe from Chinesefood.about.com. If you click on the recipe name it will take you to the website.
3/4 - 1 pound boneless, skinless chicken breasts
To Velvet Chicken:
1 large egg white
1 tablespoon cornstarch
1/4 teaspoon salt
2 tablespoons oyster sauce
1 tablespoon light soy sauce
1 tablespoon dark soy sauce
1 tablespoon water
To Cook Broccoli:
1 pound broccoli
1/2 cup water
1/4 teaspoon salt, or to taste
1/2 teaspoon granulated sugar, or to taste
2 garlic cloves
1 teaspoon cornstarch mixed with 1 tablespoon water
2 cups plus 4 tablespoons vegetable or peanut oil, for frying
1. Cut the chicken into 3/4 to 1-inch cubes. In a bowl, mix together the egg white, cornstarch and salt. Add the egg white mixture to the chicken cubes, tossing or using your fingers to coat the chicken in the mixture. Marinate the velveted chicken in a sealed container in the refrigerator for 30 minutes.
2. While the chicken is marinating, prepare the sauce and vegetables: for the sauce, mix together the oyster sauce, light soy, dark soy, and water in a small bowl and set aside. In another small bowl, mix the cornstarch and water thickener and set aside. Wash and drain the broccoli. Cut the stalk diagonally into thin slices. Cut the flowerets into 3 or 4 pieces. Crush the garlic.
3. Preheat a wok. Heat 2 cups oil in the wok until it reaches 275 degrees Fahrenheit. (Test the heat by placing a piece of chicken in the wok - it should float). Add the chicken cubes, and let cook until they just turn white (about 30 seconds), using a wooden spoon or chopsticks to gently separate them. Quickly remove the chicken cubes from the wok as soon as they turn white, and drain in a colander or on paper towels.
4. Drain the oil out of the wok or preheat a second wok on medium high to high heat. Add 2 tablespoons oil. When the oil is hot, add the crushed garlic and stir fry for 10 seconds.
5. Add the broccoli, sprinkle the salt and sugar over, and stir fry briefly, turning down the heat if necessary to make sure it doesn't burn. Add the 1/2 cup water, and cook the broccoli, covered, for 4 - 5 minutes, until it turns a bright green and is tender but still crisp. Remove from the wok and drain.
6. Clean out the wok and heat 2 more tablespoons oil. Add the broccoli and the velveted chicken, stirring and tossing to cook the chicken through. Add the sauce and cornstarch mixture in the middle of the wok and stir quickly to thicken. Mix everything together and serve hot over steamed rice.
