Method:
Preheat the oven to 350°F. In a large bowl, whisk together 1 tablespoon plus 1 1/2 teaspoons cornstarch, nutritional yeast and five-spice powder until blended. Add tofu and toss until evenly coated. Spread tofu on a parchment-paper-lined baking sheet in a single layer and bake 20 minutes or until crisp, stirring once halfway through cooking.
Meanwhile, in a small bowl, whisk together 1/2 cup Sherry, ginger, garlic, tamari, and remaining 1 tablespoon cornstarch. Set aside.
Heat a wok or large skillet over medium-high heat until hot. Add chiles and toast until fragrant, about 2 minutes. Stir in broccoli, pineapple and baked tofu and continue cooking 4 minutes longer or until just beginning to stick to the pan. Stir in remaining Sherry and cook 2 minutes, stirring. Whisk Sherry-cornstarch mixture once more, then stir in with green onions and peanuts and cook about 3 minutes longer or until heated through. Serve over rice.
