Ingredients

• 1 pound beef top sirloin steak
• 0.25 cups soy sauce
• 2 tablespoons white sugar
• 2 tablespoons cornstarch
• 0.5 teaspoons ground ginger
• 3 tablespoons vegetable oil , divided
• 1 red onion , cut into 1-inch squares
• 1 green bell pepper , cut into 1-inch squares
• 2 tomatoes , cut into wedges

Instructions

1. 1 Slice steak into 1/2-inch thick slices across the grain.
2. 2 Whisk together soy sauce, sugar, cornstarch, and ginger in a bowl until the sugar has dissolved and the mixture is smooth. Place steak slices into the marinade, and stir until well-coated.
3. 3 Heat 1 tablespoon vegetable oil in a wok or large skillet over medium-high heat, and cook steak strips in batches in hot oil so as not to crowd the pan. Cook and stir until well-browned, about 3 minutes, and remove steak from the wok to a bowl. Repeat with remaining steak, adding more oil as needed, and set the cooked meat aside.
4. 4 Return cooked steak strips to the hot wok, and stir in onion. Toss steak and onion together until onion begins to soften, about 2 minutes, then stir in green pepper.
5. 5 Cook and stir the mixture until peppers have turned bright green and started to become tender, about 2 minutes more, then add tomatoes.
6. 6 Stir everything together to mix and blend flavors, and serve.
