Heat a wok on medium high heat and add the oil. Then add the onions. Saute for 5 minutes or until they turn translucent.
Add the garlic and saute for 1 more minute. Add the string beans and saute until tender but not soggy, about 5-7 minutes. You can add 1 Tbsp of water to help soften the beans a little.
Add the soy sauce and chili crisp. Saute for another 2 minutes. Taste and adjust flavors if needed. Serve with steamed rice. Enjoy!
