In medium bowl, mix cereal, flour, baking powder and salt; make a well in middle of cereal mixture. In small bowl, mix milk, honey, melted butter, egg and lemon peel; beat with whisk to completely combine. Add liquid mixture to cereal mixture, and stir until just combined; batter may be lumpy. Stir in blueberries. Divide batter (about a heaping tablespoon each) evenly among muffin cups.
