Swedish Meatball Meatloaf

I was looking for something to make my Mom on Mother's day this year, and I thought about a meatloaf. Sometimes, they can be pretty bland, so I started thinking about how I could make a meatloaf that tasted, well, not just like a loaf of meat. Then I came across our Swedish Meatball recipe, and there it was. So here it is:

 Meat Loaf

2 Lbs. Ground Beef
2 Cups breadcrumbs
1 Onion, finely diced
2.5 teaspoons Salt
1/4 teaspoon Pepper
2 teaspoons Nutmeg
2 teaspoons Paprika
1 teaspoon dry Mustard
3 Eggs, beaten
Butter

 Heat up a saute pan and add butter. Saute diced onion in butter, until onion is soft. Combine meat with the rest of the ingredients and mix well. Let onion cool and add to meat mixture. Form meat into a loaf, and put into a baking pan. Cook at 350-degrees for 45-60 minutes, or until cooked thoroughly. While meatloaf is cooking, make the sauce.

Sauce:

 2-3 Cloves Garlic, minced
 5 Tablespoons Butter
2 teaspoons Tomato Paste
1 teaspoon Beef Concentrate
2 Cups Beef Boullion, or soup stock
1 Cup Sour Cream

 Add garlic to a tablespoon of butter and saute for one minute. Blend the rest of the butter, tomato paste, concentrate and stock. Stir over low heat until it thickens. At the last minute, add the sour cream, mix well, and serve over meat loaf.
