In a mixing bowl, mash the bananas, add the eggs and mix well. Don't worry if the mixture is a little runny.
Use a heavy-based frying pan, heated on medium heat.
Add a little butter and olive oil, when well heated, spoon a little mixture in, one at a time. When bubbling on top, turn and cook for another one to two minutes. Repeat with some more butter and oil and continue with the leftover mixture.
