Step 1

Preheat oven to 400°F. Rub cut sides of squash with 1 tablespoon oil. Place squash, cut-sides down, on a baking sheet. Roast until tender when pierced with a fork, about 30 minutes. Using a fork, scrape the squash strands into a medium bowl.

Step 2

Meanwhile, heat the remaining 1 tablespoon oil in a large skillet over medium-high heat. Add sausage and cook, using a wooden spoon to break it into small pieces, until browned, about 8 minutes. Add onion, carrots, garlic and crushed red pepper; cook, stirring often, until the onion is just translucent, about 2 minutes. Add tomatoes and broth and bring to a boil over medium-high. Reduce heat to medium-low and simmer, stirring occasionally, until the carrots and onion are almost tender, 5 to 6 minutes. Stir in kale and cook until tender, about 3 minutes. Remove from heat. Season with pepper.

Step 3

To serve, place 1/2 cup squash strands in each of 6 bowls, reserving the remaining squash strands for another use. Ladle the tomato-sausage soup around the squash in the bowls.
