Sweet and Spicy Tofu.

Tofu, red pepper, red onion and chillies, all quickly stir-fried in a sweet and sour sauce. If you like milder dishes, decrease the amount of crushed chillies or omit them altogether.

  1. Heat oil in a wok or large frying pan over medium high heat. Toss the tofu into the oil, and cook until browned on all sides. Once browned, toss in onion, red pepper, chilli and garlic; cook until just tender, about 5 minutes.
  2. In a small bowl, whisk together the hot water, vinegar, soy sauce, brown sugar, cornflour and crushed chillies. Pour over tofu and vegetables, toss to coat, and simmer 3 to 5 minutes, or until sauce thickens slightly.
