Step 5: After 10 more minutes, test that potatoes are boiled by pushing knife through one-the knife shold go through easily. Drain off water, turn heat right down, mash up adding large knob of butter, a splash of milk and small dollup of mustard and a sprinkle of pepper.
Step 6: Cut a small amount off the end of one of the sausages to make sure its cooked-it should be grey not pink. Add red onion to pan.
Step 7: Put boiling water into measuring jug and add instant gravey gradually whilst stirring untill it thickens. Add the slightly cooked red onion to the gravey.
Step 8: Serve mashed potato in the middle of the plate, with the sausages leaning against it. Pour gravey all over sausage and mash.
