Mix the eggs and yoghurt and oil together and then add to the dry ingredients .
Mix through the bananas and the walnuts .
Spray and line a loaf tin or place straight in your lined SC .
Cook on high approx 2 hours with tea towel under the lid.
Check after 1 1/2 hours. I raised mine up on two egg rings.
Note : this can be made with wholemeal SR. Flour , and substitute the sugar with 2 tablespoons of honey, also use low fat yoghurt.
