Blend one onion with the bell pepper, scotch bonnet and tomato. Keep aside
Chop the remaining onion.
Peel the yam and cut into cubes
Add into a pan with a enough water to cover the yam. Add the chopped onions with some salt and cover the pan.
Allow to cook until the yam is soft. This should take no more than 15 mins.
While the yam is cooking, prepare the plantain.
Cut the top and end of the plantain off, then cut into the skin with a knife.
Remove the skin and cut the plantain into big chunks.
When the yam is cooked, reduce the heat to low and tip out some of the water into a bowl. Keep as you may need if porridge is too thick.
Taste the yam and add more salt if required.
Add the plantain, the blended pepper mix, curry powder, ginger and palm oil.
Bring the heat back to medium.
Cover the pan and allow to cook for about 10 mins.
Reduce the heat and mash with a wooden spoon or potato masher to the consistency you prefer.
When you are happy with the consistency, stir in the spinach and cover the pan.
Remove from heat and leave for a few minutes, so the spinach can wilt before serving.
