Soak the radicchio leaves in ice water to crisp up.
Cook the rice with the garlic and herb seasoning according to package directions.
Meanwhile, heat the oil in a large skillet over medium heat. Add the carrots and scallions and saute 2 minutes. Add the pork, cooked rice, and 2 tablespoons soy sauce and cook 2 more minutes to heat through.
Spoon the pork mixture into the radicchio leaves. Serve with additional soy sauce for dipping, if desired.
