Wash the soybean sprouts and shake off any excess water before cooking.
Heat the cooking oil in the nonstick frying pan on medium-high heat. Once the oil is heated, stir in the green onion until it is fragrant, about 20-30 seconds.
Add the soybean sprouts into the pan and stir fry until the spouts are soft. Make sure you don't spill hot oil.
Add tofu slices in and continue sear for about 1-2 minutes.
Add rice wine, light soy sauce, chicken broth, and sesame oil in, and stir frequently.
Stir in the red pepper slices and green onions once the sauce has thickened.
Sprinkle salt and black pepper to taste. Transfer to a plate.
Serve with steamed white rice and enjoy!
