Heat some oil in a large frying pan over a high heat. Add the minced pork and cook for 5-6 minutes, breaking it apart as it cooks, until browned and starting to caramelise.
Add the garlic and ginger and gochujang. Cook for another minute.
Add the soy sauce, honey, mirin and sesame oil. Stir it all together and cook for a minute until the pork is coated.
Pour in the chicken stock, then add the noodles. Bring it to a simmer and cook for 3-4 minutes, turning and separating the noodles with tongs as they soften.
Toss everything together over a high heat for another minute or two until the sauce thickens and becomes glossy, coating the pork and noodles.
Spoon into bowls and finish with the spring onion, sesame seeds, and crispy chilli oil if you like.
