If you're a vegetarian or looking for a meat-free version of Gong Bao Chicken, you can try making Gong Bao Tofu. Instead of chicken, use firm tofu that has been drained and cut into cubes. Marinate the tofu in a mixture of soy sauce, rice wine, and cornstarch. In a hot wok or skillet, stir-fry the marinated tofu until it is browned and crispy. Remove the tofu from the wok and set it aside. In the same wok, stir-fry dried chili peppers, Sichuan peppercorns, and diced garlic until fragrant. Add diced ginger and stir-fry for a minute. Then, add the cooked tofu back to the wok, along with roasted peanuts and a sauce made from soy sauce, vinegar, sugar, and vegetable broth. Stir-fry everything together until the sauce thickens and coats the tofu. Garnish with sliced green onions and serve the Gong Bao Tofu hot with steamed rice or noodles. Enjoy the vegetarian version of this flavorful Chinese dish!
