To make the sauce, combine the chicken broth and soy sauce in a medium saucepan and bring to a boil.
Reduce the heat to a simmer.
In a small bowl combine the cornstarch and water and stir until dissolved.
Slowly add to the hot broth, stirring constantly until the sauce thickens.
Add the oil and cayenne and remove from the heat. Cover to keep warm.
To make the egg fu yung, combine all the ingredients except the oil in a large bowl. Stir well to combine.
In a wok or large skillet, heat 6 tablespoons of the oil over medium-high heat.
Add the meat/vegetable/egg mixture and stir-fry for 4 minutes, so that the eggs set and it lightly browns.
Remove from the heat and serve immediately with the warm sauce.
