I have made Hal's "favourite meatloaf" the same way for the last 30+ years.  One day I made this recipe and now this is the only meatloaf he wants to eat.  Some of the ingredients may seem a bit strange but the finished product is so flavourful that you will be amazed.

Method Preheat the oven to 175°C/350°F. Lightly oil a 30 x 11 x 7 cm baking pan. Prepare the vegetables: Finely chop the onion, garlic, carrot, and celery. Heat the oil in a pan over medium heat, then add the vegetables and sauté 5 min, with occasional stirring. Add a little salt, cover, then lower the heat. Cook 5 min. Take the pan off the heat, then add the Worcestershire sauce, vinegar, salt, pepper, and allspice. Finely chop the prunes then add them to the pan. Stir in the Parsley and Garlic base then mix well. In a large bowl, beat the eggs lightly, using a fork, then add the beef, bread crumbs, and milk. Mix well, then incorporate the vegetable mixture. Using your hands, blend the mixture together until it is just combined well (do not over-mix). Put the preparation into the oiled baking pan. Cook in the middle of the oven 40 min to 1 h until a thermometer inserted into the centre of the meatloaf registers 68°C/155°F. Let the meatloaf stand 5-10 min before slicing and serving.
