Heat up oil in the wok over high heat. Stir in minced meat and ginger.
Loosen the meat with a spatula. When it turns pale, add Ya Cai/Zha Cai (see note 1), dried chilli flakes & Shaoxing rice wine.
Add sweet bean sauce once the meat becomes dry. Fry for 30 seconds or so to evenly coat the meat. Dish out and leave aside for later use.
Boil the noodles & vegetable
Bring a pot of water to a full boil. Cook the noodles following the instructions on the package.
Add the vegetable for a quick blanch then drain everything.
Prepare the broth
While waiting for the noodles, heat up the chicken stock with chickpeas.
Mix all the other ingredients for the soup then pour an equal portion into the serving bowls.
Assemble the dish
Place the noodles and the vegetable in each bowl.
Add the stock. Top with chickpeas and the cooked minced meat.
Sprinkle roasted peanuts & scallion.
Notes
1. Ya Cai (芽菜, preserved mustard greens) and Zhai Cai (榨菜, preserved mustard stem) are interchangeable for this recipe. They usually come in small-sized plastic package and are available in Chinese/Asian shops.2. Sweet bean sauce can be replaced by soybean paste (Huáng Dòu jiàng, 黄豆酱) or Sichuan chilli bean paste (aka spicy Doubanjiang/辣豆瓣酱).3. For a more authentic taste, try my recipe for fresh alkaline noodles (300g/10.5oz for 2 bowls) for an even better taste. Gluten-free rice noodles work fine too.4. Depending on the saltiness of your stock, you may add a little salt to taste.5. Chongqing locals use yellow peas instead of chickpeas. The latter is more easily available outside China and provides a very similar effect. If you do have dried yellow peas, soak them overnight then cook in stock until mushy on the surface.
