I’ve done this a few times and it works. Take one banana and two eggs, whisk them together, and pour the mixture into a pan for flapjacks or pancakes. I add salt and pepper to the mix for a more savoury flavour, or you could leave this off and add maple syrup once cooked for a sweet breakfast.  I found it worked better as a thicker flapjack, than a thin pancake. I use egg rings to keep it together in the pan. You will need to play around with the sizes of your banana and your eggs to get the flavour right for your personal taste.
