How to make it
Mix the beef with the marinade and marinate for 15 minutes.
Heat a wok with oil, and stir-fry the beef over medium-high heat until 70% cooked and golden brown on the surface.
Add the soy sauce, oyster sauce, and sugar, stir-fry until well combined. Add the asparagus and red bell pepper and stir-fry until fragrant.
Add the XO sauce, shrimp roe, and walnuts, stir-fry quickly until cooked through. Ready to serve.
Add extra XO sauce to taste, if desired.
