In large microwavable bowl, place 8 cups water. Microwave uncovered on High 4 to 5 minutes or until boiling. Break noodles into 4-inch pieces, and let soak in hot water until softened, about 8 minutes. Drain; set aside.
In small bowl, stir soy sauce, 3 tablespoons water, fish sauce and cornstarch with fork. Set aside.
In medium bowl, mix chicken thighs and curry paste; stir to thoroughly coat. In 12-inch nonstick skillet, heat 1 tablespoon of the vegetable oil over medium-high heat until hot but not smoking. Add chicken in an even layer. Cook 2 to 3 minutes, without moving, until browned. Turn chicken, and cook 2 to 3 minutes longer or until no longer pink in center. Pour chicken with drippings into small bowl, and cover with foil; wipe out pan. Add remaining tablespoon of oil; place over medium-high heat, then add cauliflower and bell pepper, and cook 4 to 5 minutes, stirring occasionally, until softened.
Add soy mixture, drained noodles and chicken with drippings; stir to combine. Reduce heat to low. Simmer 1 to 2 minutes, stirring constantly, until sauce is thickened. Stir in green onions, peanuts and herbs. Divide mixture among 4 plates. Serve with lime wedges.
