When I am feeling lazy and hungry I just stick a few potatoes in the microwave. Stab them all over first with a fork (stops them bursting), spread out onto a plate (or into a microwave bowl with lid), cover (if you have a plate cover to save having to clean any spatter from the microwave), and nuke on high for about 5 minutes. I did 4 fairly small spuds last night for a snack (I could hold the 4 on the palm of my hand), and they only took 5 mins. Bigger spuds, more time (or cut in half). When done (test with a fork), slice in half, butter, sprinkle with seasoning (salt & pepper, or one of those savoury seasonings from McCormick or similar), and thin slices of tasty cheese, or whatever topping you may have, but they are my favourite lazy toppings.
