Place a large pot on medium heat and add in a drizzle of vegetable oil. Then add in the minced garlic and ginger. Fry for 1 minute until fragrant.
Next up, pour in the coconut milk and chicken stock. Grate in the lime zest and squeeze in the lime juice. Stir and season with salt and pepper.
Add the chicken breasts into the coconut mixture. Reduce the heat to medium-low and add on the lid. Simmer for 15 minutes until the chicken is cooked through (make sure the coconut milk doesn't boil over, so keep an eye on it!), then remove the chicken from the pot and set aside.
Once you've removed the chicken, taste the broth and season according to your preferences with more salt, pepper, lime juice and/or sugar. Add in the noodles and cook without the lid on, according to packet instructions.
While your noodles are cooking, shred your chicken breast in a separate bowl. Add in the chili oil, chopped parsley, and sesame seeds. Combine until well mixed.
Once your noodles are cooked, divide your noodles and broth between two bowls. Top with the chilli oil chicken. Garnish with finely sliced scallions (spring onions), sesame seeds and more chili oil (optional). Enjoy!!
