I've just discovered 1-min polenta. Not the kind from the supermarket that says it takes 20-30 mins of stirring to cook, but the stuff from European fruit shops or delis that takes only 1 minute to cook. One I have just requires the water to be boiled and the polenta to be stirred in. It makes a thick corn sludge immediately, which is perfect to serve as the carbs with chilli con carne. Haven't tried it on a bushwalk but I'm pretty sure it would be a winner. Add grated cheese for more flavour.
