Cook and drain noodles as directed on package; keep warm.
Heat oil in 12 nonstick skillet over medium-high heat.
Cook chicken in oil 4 to 5 minutes, stirring occasionally, until no longer pink in center.
Stir in dry seasoning mix, water, sugar and soy sauce.
Heat to boiling; boil 30 seconds to 1 min., stirring constantly until sauce has thickened.
Stir in noodles; toss to coat.
Before serving, sprinkle with green onions, peanuts and crushed red pepper.
Note: To really knock up the heat level, 3/4 cup szechuan sauce can be substituted for the water, sugar and soy sauce. Taste before adding any additional crushed red pepper. I doubt that you'll need it.
