Heat 1 Tablespoon oil in a saute pan.
Add yellow onion and diced pork, seasoning with salt and pepper to taste. Cook 5 minutes or until pork is no longer pink.
Add grated carrots and bean sprouts and remove from heat. Set aside to cool.
Whisk eggs in a large mixing bowl. Add meat/veggie mixture to eggs.
Stir in green onions.
Heat 2 Tablespoons oil in a skillet.
Pour 1/3 cup of egg mixture into the skillet at a time and cook 1-2 minutes on each side, until browned.
Remove patties from the skillet to a plate; continue until egg mixture is gone.
Prepare gravy by combining cornstarch and soy sauce. Mix in butter, chicken broth, and cooking sherry. Bring to a boil and boil for 1-2 minutes. Remove from heat (gravy will thicken as it cools).
Pour gravy over egg foo young and sprinkle with green onions and sesame seeds to garnish.
