This is really tasty (also from 'Feast'). It's a good way to use up overripe bananas, and it uses oil instead of butter. There is also some lemon juice and zest in it, which makes it less sweet than some other banana cakes/breads, and adds a nice tang. Very easy to make, you add wet ingredients to dry, so it's like making a big muffin.
Would be good for breakfast as it's not overly sweet, but good for any time of day.
