Bring a gallon of water to a boil, add a strong grip go salt to it and cook the wheat noodles per package instructions. When the noodles are done cooking, strain them and give them a very brief rinse with cold water to slow down the cooking. Place noodles in a bowl and toss them in a little bit of oil so they don't stick together. Set noodles aside.
Heat up 15g/1 tbsp of oil up in a wok over high heat. Stir-fry broccolini along with a pinch of salt for roughly 2 minutes, until it takes on a little color and softens slightly. Transfer broccolini to a bowl and set aside.
Wipe out any debris from the wok and return it to high heat. Pour in the remaining 15g/1 tbsp of oil and begin browning the beef. Cook and break down the beef into pea sized pieces. This should take roughly 5-6 minutes.
Once the beef is fully cooked and broken down, add in the chili crisp. Stir and scrape for 1 minute.
Stir in soy sauce, mirin, water, peanut butter, hoisin and bring it all to a simmer.
Once everything is at a simmer, toss in broccolini and noodles. Stir and toss until everything is fully combined. Adjust seasoning if necessary.
Top each portion of noodles with chopped peanuts and scallions.
