Preheat your oven to 170°C / 150°C fan oven / gas mark 3
Slice your plum in half and remove the stone. Place your plum halves cut side up in an oven dish. Drizzle them with the honey and sprinkle the cinnamon on top.
Place in the oven for around 15 mins.
After 10 minutes of roasting time, prepare the porridge as per the instructions on your packet of oats. I find that adding around 30ml of oats and 250ml water, with a pinch of salt, and bringing that to the boil, and then stirring vigorously for one minute does the trick for me. However, you might have your own preferred porridge technique that I don’t want to get in the way of!
Add a splash of milk (if you want to make creamier porridge) and stir well.
Finally, top with your honey roast plums and a few chopped walnuts and sit back and enjoy!
