1 package (14 to 16 ounces) soft or regular tofu, drained
1/3 cup chicken broth
2 tablespoons soy sauce
1 1/2 teaspoons chili garlic sauce
1 teaspoon black bean garlic sauce
1 teaspoon cornstarch
1/2 teaspoon ground toasted Sichuan peppercorns
2 tablespoons cooking oil
2 tablespoons minced garlic
1 fresh red chile pepper, minced
Combine marinade ingredients in a bowl. Add pork and mix well. Let stand for 10 minutes. Cut tofu into 1/2-inch cubes. Combine sauce ingredients in a bowl; set aside.
Place a wok over high heat until hot. Add oil, swirling to coat sides. Add garlic and chile pepper, and cook, stirring, until fragrant, about 10 seconds. Add pork and stir-fry for 2 minutes. Add tofu and sauce. Cook, stirring gently, until tofu is heated through and sauce boils and thickens. Place in a serving bowl and garnish with green onions.
