Turn on the sauté setting of your pressure cooker. When the pot is hot, add the oil and the bell peppers. Cook, stirring occasionally, until they are just becoming soft, but still have some crispness to them. Then remove them to a plate and set aside.

While meat is browning, mix up your sauce: In a small bowl add the soy sauce, ginger, sugar, garlic, salt, and pepper. Gently whisk together with a fork. Pour over the steak and stir. Cancel the sauté setting.
Pour in the broth or water. Place the lid on the pot and seal it. Then pressure cook on High pressure for 10 minutes. When done cooking, let sit 3 minutes, then release the remaining pressure until the pin in the lid drops.
