1. Heat olive oil in a large skillet over medium heat. Add sliced chicken apple sausage and sauté until lightly browned, about 3–4 minutes.

2. Add diced onion and bell pepper. Cook, stirring often, until softened, about 4 minutes.

3. Stir in the minced garlic and cook for 30 seconds until fragrant.

4. Add uncooked pasta to the skillet. Pour in chicken broth, salt, and pepper, then stir to combine and scrape up any browned bits from the bottom.

5. Bring to a boil, then reduce heat to low, cover, and simmer for 12–14 minutes, stirring occasionally, until pasta is tender and most of the liquid is absorbed.

6. Add baby spinach and cook, stirring, until wilted, about 2 minutes.

7. Remove from heat and stir in grated parmesan cheese until creamy and combined.

8. Serve immediately with extra parmesan and black pepper if desired.
