Use a sharp knife to cut the tops and tails off the green beans.
Pop the green beans in the bowl, and add the olive oil, salt, and pepper.
Toss the beans, olive oil, salt, and pepper together until the beans are coated.
Heat the grill to medium-high, and once hot, add the coated green beans. Grill for 4-5 minutes on each side or until they are charred on both sides
