Preparing green chili sauce (can be made few days before):
Place all the ingredients in a food processor and process into a smooth paste. Add a bit of water to help it goes if needed. Pour this into a small saucepan and cook for about 10 minutes. Store in a jar and will keep in the refrigerator for up to 1 week.
Preparing the crispy noodle:
Cook the egg noodles according to the instruction on the package, about 45 seconds of blanching in boiling water. Remove and rinse with cold water. Roughly form the cooked noodle into 4 pieces of about 6-7 inch size of nest-like shape. Place this on serving plates and set aside
Preheat about 2-inches of oil in a medium size skillet. When the oil is hot, lower the heat to medium. You can place the noodle in a large slotted spoon (as shown in the photo, this will help to keep the round shape) or you can just gently put the nest-like shape noodles in the oil and fry until crispy on both side. Remove and place on an absorbent paper towel. Continue with the rest of the noodles
Preparing the seafood gravy:
Preheat a large skillet or wok with 1 Tbsp of cooking oil. Add onion and cook until they are soft, about 3 minutes, add garlic and stir fry for another 10 seconds or so. Add chicken thigh pieces. Stir-fry until the chicken meat turns opaque. Add carrots and snow peas and stir fry for another 2 minutes. Now, it's time to add the shrimp and cook until they turn pink. Add tomato chunks. Cook until the tomatoes are softened. Lastly, add fish balls (these are usually already pre-cooked). Pour the gravy you have mixed earlier in. Bring it to a gentle simmer and then very slowly drizzle in the beaten in with one hand and another hand continues to stir (kinda like egg drop soup). Have a taste. Season with more salt to your taste if needed. Give the corn starch solution a stir and pour it in while one hand continue to stir. The gravy will start to thicken slightly. Turn off the heat
Ladle the seafood, veggies, and gravy generously over the crispy noodles. Serve immediately with green chili sauce
