Ingredients

Instructions

  1. Step 1: Toss 14 oz pressed and cubed extra firm tofu in 3 tbsp cornstarch until evenly coated. Heat 3 tbsp vegetable oil in a large nonstick skillet over medium-high heat. Fry tofu cubes for 3-4 minutes per side until golden and crisp. Remove tofu and set aside.
  2. Step 2: Add remaining 1 tbsp vegetable oil to the skillet. Sauté 5 minced garlic cloves and 1 tbsp grated fresh ginger for 1 minute until fragrant.
  3. Step 3: Add 1 large sliced red bell pepper and 1 large sliced green bell pepper to the skillet. Stir fry for 4-5 minutes until peppers are tender-crisp.
  4. Step 4: In a small bowl, whisk together 3 tbsp soy sauce, 1 tbsp rice vinegar, 2 tsp honey, and 1 tbsp Sriracha sauce. Pour sauce over peppers, stirring to coat and cook 2 minutes until sauce thickens slightly.
  5. Step 5: Return crispy tofu to the skillet and gently toss to combine with sauce and vegetables. Cook 1 more minute to heat through.
  6. Step 6: Remove from heat and garnish with 2 sliced scallions and 1 tsp toasted sesame seeds. Serve immediately with steamed jasmine rice.
