Spaghetti with Meat Sauce

I like this so much better than the canned spaghetti sauce. The tomato flavor isn't so strong, which is a plus for me. Definitely one I'll make again. From The Comfort Table.

2 lbs. ground beef (I only used one. That's too much meat for me)
1 medium yellow onion, grated
1-12 oz. can tomato paste
1-16 oz. can tomato sauce
2 Tbsp. sugar
2 Tbsp. chili powder
1 tsp. garlic salt
1 1/2 tsp. kosher salt
1 tsp. fresh ground black pepper
2 bay leaves
1 Tbsp. white vinegar
1 lb. spaghetti

In a stock pot combine the beef (do not brown first, onion, tomato paste, tomato sauce, 2 c. water, sugar, chili powder, garlic salt, salt and pepper. Mix until combined. Add the bay leaves. Cover and simmer over medium low heat for approximately 2 hours. Stir in the vinegar and simmer another 30 minutes. Meanwhile, cook spaghetti and then top with meat sauce. (I only used half the sauce on my spaghetti, so i froze the other half and saved it for a night when I needed to make dinner quickly.)
