Pour the oil into a deep frying pan (you’ll need one with a tight-fitting lid). Turn the heat to medium and, once the oil is shimmering, tip in the spring onions, chilli, coriander stalks, garlic, ginger and lime leaves. Sprinkle in a pinch of salt and cook for 4-5 mins, stirring, until fragrant.

Tip in the cherry tomatoes and vegetable stock, bring to the boil, then pour in the soy sauce. Reduce to a simmer and leave to bubble for 5 mins, then gently mash the tomatoes slightly using a wooden spoon. Season the fish fillets, then place in the pan, cover with the lid and cook for 4 mins.

Remove the lid from the pan and separate the noodles into the broth and around the fish. Put the lid back on the pan and cook for another 1 min on a high heat until the fish is cooked through and the noodles are hot. You will know it’s cooked because the fish will flake easily when gently pressed. Squeeze over the juice of half a lime.

Serve in bowls with a wedge of lime each for squeezing over. Scatter over the coriander leaves and serve straightaway.
