Cook the rice according to the package directions.
Heat broiler. Place the tilapia on a baking sheet lined with foil and broil, basting occasionally with the teriyaki sauce, until cooked through, 7 to 9 minutes. Break into pieces.
Meanwhile, in a small bowl, combine the cilantro, mint, scallions, and lime juice. Serve the tilapia over the rice and top with the herb salad and crushed red pepper.
