Heat cast iron skillet over high heat. Add vegetable oil and pan-fry rice cake sticks for 3 to 4 minutes per side, until lightly brown. Alternatively, toss rice cake sticks with oil in a medium bowl and broil for 3 minutes.
Mix ingredients for sauce together. In a mixing bowl, coat browned rice cake sticks in sauce and top with sesame seeds. Serve hot or at room temperature.
