1) Preheat oven at 180 degrees C/Gas 4.
2) In a medium-sized saute pan, put 2 dribbles of salad oil and heat over medium-high heat. Add the carrots, celery, and onions and saute, about 5 minutes. Put aside and let cool.
3) In a large bowl put the carrot mixture, minced beef and remaining ingredients, except for the bread, the bread crumbs and tomato ketchup. Soak the bread in cold water, then squeeze water out (like a sponge) and drain it. Add to the ground beef and mix. (A stand mixer is may help make it easier.) Add the bread crumbs and mix.
4) Roll into firm loaf, spread ketchup over the top, and place into preheated oven for approximately 45 to 55 minutes, or until cooked through.
5) Take out and serve hot.
