Put the flour in a bowl, add the yogurt, egg whites and honey to the center and mix, finally add the milk too (don't be sidetracked by the photo: I used the yogurt cup to weigh the milk).

Cook the waffles on the special plate following the instructions of the appliance and in any case until golden brown.
As they are cooked, move them to a serving dish and season with a little maple syrup.

The wholemeal waffles are ready, you just have to garnish and serve them.
