Sichuan dan dan noodles are traditionally made with ground pork, a spicy sauce and sui mi ya cai, or pickled vegetables, but this vegan version features pan-fried eggplant in place of the meat. Cutting the eggplant into relatively chunky pieces and covering the pot with a lid while cooking is the key to achieving the right texture: It locks in moisture, ensures that the pieces don’t fall apart, and allows the flesh to become tender and smoky. Once tossed with the noodles and sauce, the eggplant breaks up and becomes creamy. If you don’t have tahini, you can substitute it with smooth peanut butter or almond butter.
