Prepare noodles according to pkg. directions; drain and set aside. In a small mixing bowl, whisk together next 5 ingredients (though fish sauce); set aside. Heat 1 tbsp. oil in a large nonstick skillet over medium-high; add chicken and cook, stirring often until dark golden-brown and almost cooked through (about 4 min.). Move chicken to one side of the pan; add egg to other side. Cook eggs, stirring constantly, until barely done (1-2 min.). Remove chicken and eggs to a large bowl; set aside. Heat another 1 tbsp. oil in the same skillet used to cook the chicken; add bean sprouts, carrot, onion and garlic. Cook vegetables until crisp-tender and garlic is fragrant (2-3 min.); remove to bowl with the chicken and egg. Add remaining oil to skillet; cook noodles in oil until tender (about 1 min.). Add sauce mixture; heat through. Add chicken-vegetable mixture to pan; heat through, stirring constantly. Serve immediately with desired garnishes.
