These popular spicy potato noodles are thick, bouncy, chewy, and coated in a garlicky, savory, tangy, and mildly spicy chili oil sauce. It's incredibly delicious and irresistibly addictive, especially with a sprinkle of cilantro! This recipe is definitely fun to make for a weeknight dinner and pairs perfectly with some chicken karaage or Taiwanese fried chicken and Chinese smashed cucumber salad.
