Bring a large pot of water to a rolling boil. Add green beans to the water and blanch for about two minutes, or until the beans are cooked and still have a crisp texture.

Meanwhile, fill a large bowl with ice cold water. And keep ready.

Now, using a slotted spoon, remove green beans from the boiling water.

And transfer immediately to the ice cold water, to prevent it from cooking further.

Allow them to be in the water for about five minutes. And drain green beans and set aside.

Place a pan over medium heat, add sesame oil, and minced garlic.

Saute until garlic is fragrant.

Now add green beans, Sriracha sauce, soy sauce, red chili flakes.

Toss until the green beans coated evenly with the sauce.
