In a medium bowl mix cornmeal, flour, baking powder, sugar and salt. Add cheese, onion and red sweet pepper; toss to combine. Make a well in the center of the flour mixture. In another bowl mix egg and beer; add all at once to flour mixture. Stir just until moistened.
In a 3-quart saucepan heat 2-inches of oil to 375 degrees F. For each hush puppy, drop 1 rounded tablespoon of batter into hot oil. Fry three or four at a time for 3 minutes or until golden brown, turning once. Drain on paper towels. Sprinkle with parsley, if desired.
Meanwhile, in a small saucepan, heat pepper jelly just until melted. Serve hush puppies warm with pepper jelly. Makes 20 to 24 hush puppies.
