With damp hands, scoop a heaping tablespoon of risotto and roll into a ball. Poke a hole in center of ball with your finger. Insert a cube of mozzarella, add 1/2 tablespoon more risotto to close hole; roll to finish ball. Continue to form 12 balls.
Place flour, eggs and panko in separate bowls. For each ball, dredge in flour, shaking off excess, then dip in egg, letting excess drip off, then dredge in bread crumbs.
Fill large pot with 1 1/2" of oil on medium high. In small batches, place risotto balls into oil, turning to evenly brown all sides, about 4 minutes. Using a slotted spoon, place balls on paper towels. Top with parsley and cheese. Serve with your favorite marinara sauce. Makes 4 servings.
