In a food processor, coarsely grind sesame seeds. Add soy sauce, mirin, sesame oil, garlic, chile pepper, honey, lemon juice, and orange juice. Process for another 30 seconds.
Preheat grill to medium. Brush fish lightly with olive oil. Apply sesame-soy mixture thickly on each fillet. Grill fish until just opaque in center, about 7 minutes, turning occasionally and basting with additional sesame-soy mixture. Transfer to a platter and sprinkle with sliced scallions.
