To prepare your grilled green beans, you need to preheat a large grill pan. On the side, take a large bowl in which you can whisk the oil, soy sauce, chili garlic paste, and red pepper flakes. Then you add green beans and salt to it and whisk it all properly.

Transfer the green beans from the bowl to the grill pan and cook untill they become charred. This would take around 5-7 minutes. If you're using a grill, then place a thick layer of foil over the grates and then transfer your beans onto it.

Your green beans are ready now, take them off the heat and garnish with sesame seeds. You can also use other seasoning if you have a specific taste in mind. Have them while they are still hot!
