Marinate the beef: Clean and cut the beef into cubes. Pat dry, then season with salt, bouillon powder, and soy sauce to taste. Let marinate for 30 minutes.

Prepare the vegetables: Choose your favorite vegetables to serve with the beef. Wash, cut into cubes, and pat dry. Stir-fry briefly with a pinch of salt, then transfer to a plate.

Stir-fry the beef: Sauté garlic until fragrant, then add the beef and stir-fry to your desired doneness. Add the vegetables and stir-fry together for about 3 minutes. Transfer to a plate and sprinkle with black pepper and cilantro.

I only listed the order of seasoning. Please adjust the amounts to your taste.
