For the pea puree, soak the split peas overnight in plenty of water, drain and replace with fresh water, add the peeled, diced potato and the soup powder and cook the peas until soft.
Fry the bacon with the oil and add the finely chopped onion and fry until golden. Add the onion and bacon mixture to the pea porridge and bring to a good boil, then finely puree with a blender.
If the mash is too solid, dilute with a little water or milk. Add slices of smoked meat, heated in the puree.
