For the Paste: Make the paste from the Thai Chicken Laksa in Dinners 3 (or you can use the Curry Mee Laksa paste). If you are using some store bought Laksa paste, check the jar or packet for how much to use for 3-4 servings.
Boil ramen noodle cakes in a pot of water according to packet instructions (usually 3–4 min), then drain and set aside. Take care not to over cook to soft noodles.
Heat a splash of oil in a large pan or wok over medium-high heat. Add the chicken and cook until browned and cooked through (about 6–8 min). Remove and set aside.
In the same pan, add a little more oil. Sauté the onion for 1–2 min until softened, then add the frozen veg. Stir-fry for 5–7 min until heated through and slightly charred in spots. Set aside with chicken.
Add the remaining oil and laksa paste. Cook off for 3 min until fragrant. Reduce heat to low and add soy sauce, brown sugar, chicken stock concentrate, and coconut milk. Stir to combine.
Add the chicken and veg back to the pan along with the sauce. Let it bubble for a few minutes until thickened slightly.
Toss in the cooked ramen noodles and mix well to coat everything in the sauce. Stir-fry for another 1–2 min to heat through.
Serve hot with a squeeze of lime and fresh coriander or spring onion.
