To make Slow Cooker Pasta e Fagioli, you really are just adding everything to your slow cooker and letting your crockpot do the work.  Add the minced garlic, diced onion, celery and carrots to your slow cooker.  Stir in the beef broth and spaghetti sauce along with your spices, herbs and beans.  Add in the leftover hambone and submerge as much as possible. Cover and cook on High for the first hour then drop to Low for the next 6 - 7 hours.  Before serving, bring a large pot of salted water to boil and cook ditalini following manufacturers instructions on the box.  Drain pasta and serve up with your Slow Cooker Pasta e Fagioli soup.
