Peel one orange and take out the pips.
Put the orange flesh into a blender. Add the eggs, milk, vanilla and pulse for a few seconds until you get a purée. Add the oats, ground almond and baking powder, then pulse again. Add more milk if needed - you should get a thick, but pourable batter.
Heat the waffle maker. Once it’s hot, spoon in some batter and seal. Following the machine instructions, cook the waffles for about 3-5 minutes - they should be golden and crispy on the outside, soft inside. You should be able to get 3 or 4 waffles from the mixture (depending on the size of your machine).
Meanwhile, peel the other orange and cut into thin slices. Heat a drop of oil in a non-stick pan, then add the orange slices. Drizzle with some honey and cook for 2 minutes, then turn them over and cook until they are slightly caramelized.
Serve the waffles warm with the caramelized orange, the pan jus and a drizzle of honey.
