In a bowl, mix the ground chicken with green onions, crushed Maggi cube, chicken powder, oyster sauce, sugar, white pepper, olive oil, cornstarch, and MSG until well combined.
Transfer the mixture to a zip-top bag and snip off a corner. Pipe a log along the edge of a seaweed sheet and roll it up tightly into a cylinder. Repeat with the rest.
Whisk the flour and water into a thin, smooth batter.
Dip each roll in the batter to coat, then deep-fry in hot oil until golden, crispy, and cooked through.
Drain, slice if you like, and serve hot with a dipping sauce.
