I use the steel cut oats with some dried cranberries and a little brown sugar. This method isn't for everybody, but I put about 1 cup into a mason jar with enough water to cover the oats by ~4 cm. Leave it in the 'fridge overnight and then in the morning I microwave it until hot, add the cranberries and sugar. Works for me when I bike commute as it is super simple. But the texture is a bit different and many folks don't like this method.
