Place the chopped potatoes in a pot of boiling water and cook until soft. Strain the potatoes and place back in the pot. Add the butter, a pinch of salt and pepper and mash until smooth. Set to one side.
Heat the oil in a saucepan. Add the onions and cook for 10 minutes until the onions are soft and slightly brown.
Add the beef stock. Bring to the boil and add the gravy granules and cook for a further 5 minutes. For thicker gravy add more granules.
Fry the sausages until golden brown and cooked through.
Plate the mash potato and sausages and pour over the onion gravy.
Serving Suggestion: For a gourmet touch add a splash of red wine to your gravy.
