Ready to bring this dish to life? Follow these steps:

1. Cook the penne pasta according to package instructions until al dente. Drain and set aside.
2. In a large skillet, heat the olive oil over medium-high heat. Add the chicken pieces and cook until browned, about 5-7 minutes. Remove and set aside.
3. Add the sliced sausage to the same skillet and cook until browned, about 3-4 minutes. Remove and set aside with the chicken.
4. In the same skillet, add the chopped onion, red and green bell peppers. Sauté until the onion is translucent, about 5 minutes.
5. Stir in the minced garlic and cook for another minute until fragrant.
6. Add the diced tomatoes, chicken broth, Cajun seasoning, paprika, thyme, oregano, salt, and pepper. Stir to combine.
7. Return the chicken and sausage to the skillet. Bring the mixture to a simmer and allow it to cook for about 10 minutes, letting the flavors meld together.
8. Stir in the cooked penne pasta and heavy cream. Cook for another 2-3 minutes until heated through.
9. Garnish with sliced green onions before serving.

Remember, cooking is an art, not a science. If you want more spice, add a pinch of cayenne pepper. If sweeter notes are more your thing, a dash of sugar can balance the heat beautifully.
