Filipino Beef Stir-Fry

Place the sliced steak in a large bowl. Sprinkle the cornstarch over the beef slices and mix to coat. Whisk the soy sauce and sugar together in a small bowl until the sugar dissolves; pour over the beef slices. Mix and marinate in the refrigerator for at least 2 hours or overnight.

Heat 3 tablespoons olive oil in a large skillet over medium heat; cook and stir the onion and garlic in the hot oil until tender 5 to 7 minutes. Stir the oyster sauce into the onion and garlic; season with salt and pepper. Add the snow peas green peas carrot celery and red bell pepper; cook and stir until the vegetables are slightly tender yet still crisp 7 to 10 minutes. Remove the skillet from the heat.

Heat 2 tablespoons oil in a separate skillet. Remove the beef from the marinade shaking off any excess moisture; discard the marinade. Fry the beef slices in the hot oil to your desired degree of doneness 3 to 5 minutes per side for medium. Add the cooked beef to the vegetable mixture and mix well. Serve hot.
