As usual I had to come up with something to use up last night's mashed potato. I had a courgette (zucchini) and a capsicum (bell pepper), so I halved the capsicum and the courgette and hollowed the seeds out a bit. I also removed the white bits and seeds from the capsicum.
I cooked the courgette and capsicum in a moderate oven for about 15 minutes.
I then spooned in the mashed potato and then grated a bit of good parmesan cheese over them.
I finished these off in the oven – they weren't quite as golden brown as they could have been but my patience ran out. And they tasted just fine as they were.
