Place a large soup pot over medium-high heat, and drizzle in about 2 tablespoons of oil; one hot, add in the sliced sausage in a single layer, and allow it caramelize and brown on that first side (a few minutes), then stir and allow it to further caramelize for about another 2 minutes.
-Add in the onion, and stir to combine; saute together with sausage for about 3-4 minutes, until lightly golden; add in the Italian seasoning, paprika, black pepper, and pinch of salt, plus the garlic, and stir to combine.
-Next, add in the carrots, parsnips, celery, potatoes, and butternut squash, and stir to combine with the sausage and onion mixture; next, add in the chicken stock, and bring to the boil.
-Reduce the heat to medium-low, and allow the stew to simmer, uncovered, for 40 minutes (it can bubble, but don't have it simmering too, too vigorously).
-Turn off the heat, and check to see if any additional salt/pepper is needed; add in the kale and the chopped parsley, and stir to combine, allowing the kale to wilt into the soup for a few minutes before serving; serve with good quality bread.
