Chop your carrots into similarly sized pieces and dice onion, add to crockpot.
Remove casing from sausages. Add sausage meat, egg, garlic, parmesan (optional), and bread crumbs into a bowl and mix well.
Create small meatballs that are about teaspoon sized and cook on a cookie sheet or put 1 meatball into each hole of your mini muffin pan (I do it this way) in the oven for about 15 minutes at 350 degrees.
Once cooked add to crockpot and cook for approx 6-8 hrs. on low.
About 15-20 min. before serving add pasta and chop about 10 pieces of escarole (I just use dark ends) into strips and add that too. Serve!
