1. Preheat oven to 375º. Spray five muffin cups generously with cooking spray, or use muffin liners. Fill any empty cups with water.
2. Combine cornmeal, flour, sugar, dry mustard, baking powder, and salt in a medium-size bowl. Add milk, egg, and margarine. Mix until smooth.
3. Cut hot dogs into 1-inch lengths. Spoon about 1/4 cup of batter into each prepared muffin cup. Place 3 hot dog pieces in each muffin cup.
4. Bake for 20 to 30 minutes, until toothpick inserted into the muffin comes out clean.
How kids can help: Mix ingredients, spoon batter into muffin cups, and add hot dogs.
