I usually love to recommend non enameled cast iron pans.
Those are the pans I use most and I am pretty lazy myself.
Most times I just clean them with soapy water and a sponge, dry them well, rub a really really small splash of oil around in it and heat it back up until I see the first signs of smoke.
If even that is too much work (and you have a gas stove or similar) I would recommend a simple wok from any Asian store.
I have a glass stove top right now so I rarely use mine anymore, but if I had a gas stove I think that I would use it all the time.
