- 3 tablespoons peanut oil
- 1 pound firm tofu, cubed
- 1 red onion, sliced
- 1 red bell pepper, sliced
- 1 green chile pepper, chopped
- 3 cloves garlic, crushed
- 1/3 cup hot water
- 3 tablespoons white vinegar
- 3 tablespoons soy sauce
- 1 tablespoon brown sugar
- 1 teaspoon cornstarch
- 1 teaspoon crushed red pepper flakes
- Heat peanut 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, bell pepper, chile pepper, and garlic; cook until just tender, about 5 minutes.
- In a small bowl, whisk together the hot water, vinegar, soy sauce, brown sugar, cornstarch, and red pepper flakes. Pour over tofu and vegetables, toss to coat, and simmer 3 to 5 minutes, or until sauce thickens slightly.
