Blend the cooked broccoli to make a puree.

In a bowl, mix the flour and salt. Add the eggs, then gradually add the milk while stirring to avoid lumps.

Add the olive oil, broccoli puree, and grated cheese.

Heat a waffle iron, lightly oil it if necessary, then pour a ladle of batter.

Cook for 5 to 7 minutes until the waffles are golden brown.
