In a large bowl, whisk together the flour, cornmeal, sugar, yeast and salt. Add in the milk, eggs and butter. Whisk until thoroughly combined. Cover the batter loosely with plastic wrap and place in the refrigerator to chill overnight (or up to 24 hours).
Preheat a waffle maker. Stir the batter and then pour the recommended amount into the waffle maker according to the manufacturer’s instructions. Cook until golden brown. Repeat with the remaining batter.
To serve, top each waffle with a fried egg, desired amount of salsa and a few slices of avocado.
