I found this online somewhere a year or so ago and have tweaked only slightly...
Brown up a pound of ground beef (or turkey)
add a diced onion and cook until onion is translucent then put into crockpot with the following ingredients:
1 can Cannelini beans (rinse/drain)
1 28 oz can diced tomatoes (do not drain)
1 C leftover spaghetti sauce (or small can of Ragu or tomato sauce with the Italian herbs)
3 carrots - chopped
3 ribs celery - chopped
1 box of beef broth
1 tsp EACH: oregano, thyme, parsley
cook on low for 8 hours.
When you get home, add 1/2 box of pasta shells, crank the heat up to high for 30 minutes. The pasta will have cooked and soaked up much of the broth.
Serve with a salad and a nice, hot loaf of Italian bread.
SO satisfying after a soccer game on a chilly night!
