1. Preheat the grill to high.
2. Trim the tips off the stems of the okra, but do not cut into the pods. Lay 5 pieces of okra side by side in a neat row at the edge of a cutting board. Skewer crosswise with 2 bamboo skewers, one at the top, one at the bottom. Lightly brush the skewered okra with sesame oil and season with salt and pepper.
3. Grill the okra until tender and lightly browned, 3 to 5 minutes per side, turning once with a flat spatula. Serve the okra at once, letting each guest remove the skewers.
