Found this on netmums, which looks nice. Haven’t tried it, but I think I will soon. If you do, let me know how you get on!
2 eggs
50g butter
150g grated cheese (use less cheese or reduced fat cheese if preferred)
150g porridge oats
All you need to do is mix the ingredients and press into a greased 8 inch/20cm tin. Get your children to join in if they fancy it. Then bake for about 30 to 40 minutes at 180C/Gas 4 until golden brown.
Once it’s cool, cut it into slices.
Variation: add some grated or finely chopped veg.
Suitable for freezing
