Heat olive oil in a large pot. Add sausages and brown. Remove from the pot, transfer to a bowl, and refrigerate.

Add onions, celery, carrots, and parsnips to the pot (and additional olive oil if necessary). Sweat for five minutes. Add minced garlic and cook for one minute, until fragrant. Add diced tomatoes and water or broth; bring to a boil.

Lower to a simmer and cook for 25-30 minutes. Toss in pasta, kale, and sausages. Cook for an additional 15 minutes.
