Dan Dan Noodles

In a large pot of boiling salted water, cook noodles according to package instructions. Add greens 1 minute before the noodles are ready. Drain, rinse under cool water, and drain again. Divide noodles and greens between 2 bowls.

Mix pork with five-spice powder and 1/2 teaspoon salt. Heat oil over high in a large skillet. Add pork in 1 layer and fry, breaking up pieces with a wooden spoon, until crisped and beginning to brown, 6 to 8 minutes. Add ginger, garlic, and scallions and cook until fragrant, 1 minute. Stir in wine, soy sauce, and tahini, scraping up any browned bits from bottom of pan. Add chicken stock. Cook until thickened slightly, about 4 minutes. Divide pork mixture evenly between the bowls. Drizzle generously with chili oil and sprinkle with peanuts and scallions. Mix thoroughly before eating.
