Step 1: Put the potatoes on to boil in salted water.
Step 2: heat a pan that can be used on a hotplate and under the grill.
Step 3: cook the meat with the onion, breaking the meat up with a wooden spoon, until the meat has browned.
Step 4: add the carrot, peas, tomato puree, stock granules and worcester sauce, stir to mix and add just enough water to keep the mixture in the pan liquid.
Step 5: put a lid on the pan and cook for 5 minutes approx.
Step 6: sprinkle the flour over the mixture in the pan and stir to combine. Continue to cook for about two minutes, stirring from time to time.
Step 7: gradually pour about half a mug of water from the potato pan into the meat mixture and stir carefully. The liquid will thicken to make a ‘gravy’.
Step 8: when the potatoes are cooked, mash with a little butter or low fat spread, and milk.
Step 9: spoon the mashed potato over the meat in the pan.
Step 10: while everything in the pan is still hot, put it under the grill to brown.
