Finely slice the beef intestines into thin pieces.
Slice the beef against the grain into thin strips, then further cut each strip into paper-thin slices at an angle for maximum tenderness. The goal is to cut the meat finely, not mince it.
Combine the thinly sliced beef with blood, salt, MSG, fish sauce, Thai chili flakes, toasted rice powder, and beef bile in a mixing bowl. Make sure the salad dressing is well mixed.
Toss in chopped green onions, cilantro, and mint, then mix gently. Serve immediately.
