Quick Sunday Sauce

What do you do with all of that extra roast from the Lazy Cook's Pot Roast?! You make Quick Sunday Gravy! This sauce was to die for and took that pot roast to another realm!

Easy Sunday Sauce 
adapted from Cook's Country February/March 2011 
1 tablespoon olive oil
1 pound ground Italian sausage, out of casing (I use sweet, but hot would be yummy too!)
2 medium onions, chopped
2 tablespoons tomato paste (I freeze the rest)
6 garlic cloves, minced
2 teaspoons sugar
1 teaspoon dried oregano
1 teaspoon dried basil
1/4 cup beef (or chicken) broth
1 can crushed tomatoes
2 cups shredded leftover chuck roast meat
salt and pepper to taste
1 pound of cooked pasta (I prefer penne rigate, or some other tubular pasta)

Heat oil in Dutch oven (or large pot) over medium heat. Add sausage and cook until browned. Drain.
Cook onions in sausage fat over medium heat until see through. Add tomato paste, garlic, sugar and spices. Cook until tomato paste begins to darken, 1 to 2 minutes. Add broth, scraping up all of the brown bits and simmer until reduced to about 2 tablespoons, about 1 minute. Add tomatoes, roast, reserved sausage, 3/4 teaspoon salt and 1/4 teaspoon pepper. Reduce heat to low and simmer, covered, until slightly thickened (at least 20 minutes...this is when I start to cook the pasta). Season with salt and pepper and serve over pasta.
