Preheat the slow cooker if necessary - see manufacturer's instructions. Grease a baking dish or tin that will fit comfortably in the slow cooker pot.

Heat the oil in a frying pan and fry the meat and onion over high heat until browned.

Add the rest of the ingredients and stir well.

Spoon the mixture into the baking dish or tin and place in the slow cooker pot. Pour boiling water into the slow cooker pot so that it comes halfway up the sides of the baking dish.

Cover and cook on high for 5 - 6 hours until the meat loaf is cooked through.

Serve hot, warm or cold.
