01 - Press tofu for at least 10 minutes to remove excess moisture, then cut into bite-sized cubes.
02 - Toss tofu cubes with cornstarch until evenly coated on all sides.
03 - Heat 2 tbsp oil in a large skillet or wok over medium-high heat. Add tofu cubes in a single layer and fry until golden and crispy on all sides, about 8 to 10 minutes. Remove and set aside.
04 - Add remaining 1 tbsp oil to the pan. Sauté green beans for 3 to 5 minutes until bright green and slightly tender but still crisp.
05 - In a small bowl, whisk together soy sauce, black pepper, maple syrup, rice vinegar, sesame oil, garlic, and ginger until well combined.
06 - Return tofu to the pan with green beans. Pour in the sauce and toss to coat everything evenly. Stir-fry for 1 to 2 minutes until heated through and sauce thickens slightly.
07 - Garnish with toasted sesame seeds and sliced scallions. Serve hot alongside steamed rice or noodles.
