Brown the sausage with the onion and garlic in a skillet.
White the sausage is browning, add the broth, oregano, kale, sun dried tomatoes, and salt and pepper (think about how much salt is in your broth before adding) to the crockpot.
When the sausage and veggies are browned, add them to the crockpot and set on low for 2-3 hours.
Right before serving add a half cup of half and half to your soup and mix it. Add a bit more if you like. Taste and adjust for seasonings.
Serve warm with shredded parmesan and chopped fresh parsley on top.
