Soak the rice noodles in warm water for about 15-20 minutes until they're pliable but still firm.
While the noodles soak, marinate sliced chicken in a bit of soy sauce and cornstarch.
Heat your wok or large skillet over high heat. Add oil and quickly stir-fry the chicken until it's nearly cooked through.
Push the chicken to one side and crack in the eggs. Scramble them slightly, then mix with the chicken.
Add garlic, shallots, and dried shrimp (if using). Stir-fry until fragrant.
Drain the noodles and add them to the wok. Pour in your prepared sauce and toss everything together.
Add bean sprouts and garlic chives. Toss until the noodles are cooked but still chewy.
Serve hot, garnished with crushed peanuts, extra bean sprouts, and lime wedges.
