• ½ kilo sirloin, sliced thin and cut into strips
• 1 onion, peeled and sliced thinly
• 4 cloves garlic, peeled and minced
• ¼ cup oyster sauce
• ¼ cup soy sauce
• ½ cup water
• 1 tablespoon sesame oil
• 2 tablespoons oil
• 1 teaspoon cornstarch
• 1 teaspoon sugar

Instructions

1. Cut ampalaya lengthwise into halves. With a spoon, remove seeds and scrape off inner pith. Sliced thinly and place in a bowl of cold water until needed. Drain well when ready to use.
2. In a bowl, combine the beef, half of the oyster sauce, half  of the soy sauce, sesame oil and salt and pepper to taste. Marinate for about 8 minutes.
3. In a pan, heat 1 tablespoon of the oil. Add the beef, allow to sear for about 1 to 2 minutes or until lightly browned both sides. Remove from pan and set aside.
4. In the same pan, add the remaining 1 tablespoon of oil. Add onions and garlic and cook, stirring regularly, until limp. Add ampalaya and gently stir to combine. Cook for about 2 to 3 minutes or until tender yet crisp. Return beef to pan.
5. In a bowl, combine the water, the remaining soy sauce and oyster sauce, sugar and cornstarch. Stir until sugar and cornstarch are dissolved. Add to pan and continue to cook, stirring regularly, for about 1 to 2 minutes or until beef is heated through and sauce slightly thickens. Season with salt and pepper to taste.
