To ensure a delightful texture, use firm tofu for this stir-fry. Cut the tofu into bite-sized cubes and pat them dry with a paper towel to remove excess moisture. Lightly season the tofu with salt and pepper or marinate it for extra flavor. Pan-fry the tofu until golden and crispy on the outside while remaining creamy on the inside. This step adds a wonderful contrast of textures to the dish.
