Meatloaf

I know, you either love it or hate it right? The meatloaf of my childhood was good, but pretty much inedible without a healthy slathering of ketchup all over it. You can eat anything if you like ketchup. :)

Unfortunately, my ability to slather things with ketchup has gone the way of the Dodo. Thus, I had to find a new recipe that wasn't just like eating a loaf of meat with no other flavor.

Tada!

Meatloaf
1 lb ground beef
1 egg
1/2 c oats
1/4 c chopped onion (or ~1/2 T of dried)
2 Tbsp brown sugar
1/2 tsp garlic powder
1/4 tsp salt
1/4 tsp pepper

Mix all the dry ingredients and then add the egg while the meat is defrosting. Then mix in the beef (I definitely recommend mixing the dry ingredients first, otherwise you end up with a loaf that's really salty in one place and sweet in another). Press that mixture into an 8x4x2" loaf pan. Bake at 350˚ until a meat thermometer reads 165˚ (~45 min). IMPORTANT: Ground beef is very dangerous. Mucho bacteria-o. Be sure your thermometer reads at least 165˚, don't just go off of the color of the meat.

Problem. This recipe is made to be slathered in BBQ sauce. I simply leave that off (though the hubby doesn't). The problem is that for me, the meat is almost too sweet. I don't have that tangy flavor of the BBQ sauce to balance it out. Any ideas on how to balance this recipe w/o using tomatoes? Or acid-laden sauces? Or vinegar? (You see my problem?)
