Instructions

Step 1: Toss 14 oz cubed firm tofu in 1 tbsp cornstarch until evenly coated. Heat 3 tbsp vegetable oil in a large skillet over medium-high heat and fry the tofu for 5-6 minutes, turning occasionally until golden and crisp on all sides. Remove and set aside.
Step 2: In the same skillet, add 5 minced garlic cloves and 2 finely chopped fresh red chilies, sautéing for 1 minute until very fragrant but not burnt.
Step 3: Add 1 sliced red bell pepper and 1 1/2 cups broccoli florets, stir-frying over high heat for 4 minutes until vegetables are crisp-tender.
Step 4: Mix 3 tbsp soy sauce, 1 tbsp rice vinegar, 1 tsp brown sugar, 2 tsp sesame oil, and 1/4 cup water in a bowl, then pour this sauce into the skillet, stirring to coat the vegetables.
Step 5: Return the tofu to the skillet, toss gently to combine all ingredients, and cook for another 2 minutes until the sauce thickens slightly and glazes the tofu and vegetables.
Step 6: Garnish with 3 sliced green onions and serve immediately with steamed rice or noodles.
