Remove the bean sprouts from the packaging and rinse them in cold water to remove any dirt. Remove the fibrous root section and drain the washed bean sprouts in a colander to remove excess water.

Prepare the chopped garlic and cut the green onions into 2-inch sections. Cut the red chilies into rings and firm tofu into strips.

Heat oil in a large wok or skillet with raised edges. Sauté the chopped garlic until fragrant. Then add the tofu to stir-fry for a minute. Remove from the wok.

Add the bean sprouts to the wok. Turn up the heat to medium-high and continue stir-frying for a minute. Pour the seasoning into the bean sprouts, and continue stir-frying for a minute or until they are just crisp-tender.

Return the tofu, red chilies, and green onion to flash fry for ten seconds. Remove them immediately to prevent overcooking.
