Other things made from Banana nut bread
You can make pretty much any bread-like substance into french toast (slice the bread, dip or soak in eggs mixed with a little milk, then shallow-fry in your choice of fat) or bread pudding (cube the bread, if necessary spread it out to dry and/or toast it, pile it in a baking pan, cover in a milk + egg + sweetening mixture, bake). Heck, if you're feeling really decadent (or you can't make up your mind), you can make french toast bread pudding: fry the bread, then make it into bread pudding.
