Diva's Sweet and Sour Meat Loaf

Diva’s Memories of Recipes Sweet & Sour Meat Loaf
Inspiration:  My Grandma Z gave me a cookbook in 1979 that I have been using all these years.  This is one of those recipes that is stained and tattered from wear and tear:) It's delish!!!
Ingredients: 1~1/2 lb ground beef 1 cup bread crumbs 1 tsp salt 1/4 tsp pepper 2 TB vinegar 1 15oz can tomato sauce 1 small onion, chopped 2 TB brown sugar 1/2 cup white sugar 2 tsp prepared mustard 1 tsp parsley	Instructions: Mix ground beef, bread crumbs, salt, pepper, parsley, onion and 1/2 of the tomato sauce.  Form into loaf, wrap in foil and put into loaf pan.   Bake in a 350 degree F oven for 50 minutes. Mix remaining ingredients in a medium saucepan and bring to a boil and all is dissolved. Pour over meatloaf after the 50 mins and bake another 30 minutes.
Variation:  I always drain the surplus grease before adding the sauce if any is present.  I also cook this with cut up potatoes, onion and carrots.  The sauce gives the veggies a wonderful flavor.
