We do the "porridge pancakes" in the microwave too. I usually cut them up then drizzle a bit of flax, hemp or fish oil over to give some healthy fats.
Another thing my LO loves is 1/4 flaxseeds ground in the coffee grinder, 1 egg, pinch of salt and 1/4 t baking powder. Mix really well in a microwave proof bowl then spread it out flat and cook for 1-2 minutes.
It comes out like a thick slice of bread, but is way healthier
We do sweet potato soldiers to dip in a boiled egg too.
My LO doesn't like sweet things either, but loves fruit, so sometimes I give him puffed cereal from the organic shop which is just the puffed grain/seed quinoa, buckwheat or rice nothing else added. I then mix it with some pureed fruit.
