6 cups quartered Brussels sprouts 2 teaspoons olive oil 1 chopped green onion ¼ cup Kikkoman Gluten Free Soy Sauce 2 tablespoons Kikkoman Rice Vinegar 1 tablespoon sugar ¼ cup water 1 teaspoon corn starch 8 dried Chinese red chilis ½ teaspoon crushed red pepper flakes, or more depending on preferred spice level ½ teaspoon ground black pepper 3 tablespoons peanuts 4 cloved minced garlic 1 tablespoon grated ginger
Preheat oven to 450° F. Toss Brussels sprouts with olive oil and place in a single layer on a baking sheet. Roast until tender and slightly crisp, about 25 minutes. Remove from heat and set aside.
While the sprouts are cooking, whisk together the green onion, soy sauce, rice wine vinegar, sugar, water, and corn starch in a small bowl. Set aside.
Right before the sprouts are done cooking, heat a wok over medium-high heat. Add in the chilis, red pepper, and black pepper and cook until fragrant and toasted, stirring often, about 2 minutes. Add in the peanuts and cook another minute until toasted.Reduce heat to medium and add in the garlic and ginger and cook another minute, taking care not to burn. Add the corn starch mixture to the wok. Cook for 4-5 minutes until thickened, stirring occasionally.
Add in the cooked Brussels sprouts and toss until hot and coated with the sauce. Season to taste for heat. If more is desired, add in an additional ¼ teaspoon or more red pepper flakes.
