You will have seen these online everywhere, I shouldn't wonder, with massive great headlines: she made these wonderful pancakes with just two ingredients, or similar.
But the point is, they are delicious, and they are easy, and you can make them for afternoon snack with your five-year-old grandson in a very few minutes.
You simply whisk 1 egg per small, or 2 eggs per large ripe banana together until everything is smooth - my daughter, at whose house I was making these, had small bananas, so we mashed them first and then whisked them until they were more-or-less smooth. Then I heated some oil in a frying pan - not a lot, only about a tablespoonful, if that, and when it was hot we ladled tablespoonfuls into the pan. You cook them like drop scones or Scotch pancakes, nice and thick. It looked disgusting in the frying pan. The Boy said it looked like custard, but actually, it looked like puke (it was not as smooth as it could be, and the bananas were somewhat over-ripe). Anyway, once they are dry-ish on top, you turn them over and cook the other side until golden, and serve immediately. A professional cook would probably dust these with icing sugar, but they are actually sweet enough as it is, and really don't need anything with them. And of course they tick all the boxes by being gluten-free, low carb and no added sugar! And vegetarian....
Well worth doing. Even my grandsons, who don't like eggs much, like these.
