Pepperoni Muffin Bites

Heat the oven to 400º and line about 36 mini muffin cups with paper liners. Sift the flour, cornmeal, sugar, baking powder, and salt into a large mixing bowl. In a separate bowl, blend the egg, milk, and vegetable oil. Make a well in the dry mixture and add the liquid. Stir the batter until smooth. In a small bowl, blend the marinara sauce and Parmesan cheese; set aside. Spoon the batter into the muffin pan liners, filling them about three quarters full. Spoon about 1/2 teaspoon of the sauce-and-cheese mixture on top of each one, pushing it in slightly, then sprinkle with chopped pepperoni. Bake the muffins for 15 minutes; they'll puff up and brown slightly around the upper edge. Cool in the pan for several minutes, then remove from the pan and eat warm. Makes about 36 mini muffins.
