Beef with Vegetables

In a large skillet over medium high heat, saute the beef slices in the oil for 5 minutes, or until well browned. Add the onion, garlic and ginger and saute for 5 more minutes. Then add the green bell pepper, carrot and beef broth. Reduce heat to low and let simmer.

Meanwhile, in a separate small bowl, combine the corn flour, sugar, soy sauce and oyster sauce, if desired. Stir thoroughly, forming a smooth paste. Slowly add this to the simmering beef and vegetables, stirring well, and let simmer to desired thickness. Season with salt and pepper to taste.
