This is a low calorie soup with a lot of greens and veggies. It's a bit spicy from the sausage, but you can substitute plain ground turkey for the sausage. This recipe changes every time I make it - I put a lot of leftovers into the pot, but it always turns out delicious. Serve a big bowl with focaccia bread as a meal, as a starter, or as a quick lunch. This soup freezes and reheats well.
