Prep:
- Make the sauce: Whisk together the oyster sauce, low sodium light soy sauce, chinkiang vinegar, chili oil, sesame oil and white sugar in a small measuring cup (for easier pouring) or bowl until combined well.
- Prepare all the fresh ingredients: Prepare the yellow onion, spring onion, garlic, ginger, fresh red chilies (if using) and Chinese broccoli as indicated in the ‘ingredients’ section.
Sichuan Pork and Broccoli Noodles:
- Prepare the noodles: Bring a medium-sized pot of water to a boil. Lower the heat to medium-low and place the udon noodle cakes in the pot of hot water. Use tongs to hold onto the noodle cakes and gently shake until the noodle strands have separated and are tender – about 1-2 minutes. Drain into a colander and run cold water on the noodles to prevent sticking and halt the cooking process. (If using frozen udon, you can use the same process. For dried udon noodles, prepare according to package instructions.)
- Stir-fry the onions: Heat 2 teaspoons of peanut oil in a large nonstick wok or heavy bottomed deep edged skillet over high heat. Add the yellow onion, spring onion white and light green parts and ginger. Stir-fry for 30-40 seconds until the onion is translucent.
- Stir-fry the aromatics: Add the garlic and red chilies and stir-fry for 30 seconds until fragrant.
- Cook the pork: Move everything to the back of the wok and add the ground pork and ground Sichuan red peppercorns. Stir-fry for 2-3 minutes, breaking up the clumps, until just cooked. Toss to combine with everything else.
- Add the Chinese Broccoli: Add the Chinese broccoli and season with ⅛ teaspoon sea salt. Stir-fry to combine until the dark leafy green parts begin to wilt.
- Add the cooked noodles and sauce: Add the cooked udon noodles and pour the prepared stir-fry sauce on top. Stir-fry for 1-2 minutes, until everything is evenly coated in the sauce and it has mostly been absorbed.
- Toss through the spring onion: Toss through most of the spring onion dark green parts. Switch off the heat.
- To Serve: Divide evenly on plates or in bowls. Garnish with the reserved spring onion dark green parts and serve immediately!
