Bring beef to room temperature for 10 minutes, trim tendons, and season with salt and pepper.

Slice green onion diagonally into thin pieces.

Crack 3 eggs into a bowl and mix. Reserve 1/2 egg for batter preparation.

Coat beef in flour, then dip in the reserved beaten egg, and finally cover with breadcrumbs.

Heat vegetable oil in a pot to 180°C and fry the beef for about 1 minute until golden brown. Slice into 7mm pieces while hot.

In a small frying pan, heat the seasoning ingredients over medium heat until boiling. Add green onion and cook until softened. Pour in the remaining 2 1/2 eggs and cook until partially set. Arrange beef slices on top, cover, and let steam off heat until eggs reach desired doneness.
