If you're a vegetarian or simply looking for a meat-free version of Dan Dan Noodles, this recipe is for you. Instead of using minced pork, this vegetarian version uses tofu as a protein source. The tofu is marinated in a flavorful sauce and then stir-fried until crispy. The noodles are cooked separately and then tossed in a spicy sauce made from chili oil, Sichuan peppercorns, and other seasonings. The crispy tofu is then added to the noodles, along with a garnish of chopped scallions and peanuts. This vegetarian Dan Dan Noodles recipe is just as delicious and satisfying as the classic version, but without the meat!
