Lay out thinly sliced beef and sprinkle herb salt evenly. Let it rest for seasoning.

Prepare vegetables by slicing bell pepper, trimming green onions, and cleaning enoki mushrooms.

Place a slice of seasoned beef flat and layer prepared vegetables on top.

Roll the beef tightly around the vegetables to form rolls.

Lightly coat the rolls with glutinous rice flour to help them hold together.

Heat a pan with oil and pan-fry the rolls, turning them to cook evenly.

Mix water, soy sauce, oligosaccharide, sugar, and mirin to create the sauce.
