Creating Creamy Cajun Chicken Pasta is straightforward if you follow these simple steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the fettuccine and cook according to package instructions until al dente. Drain and set aside.

2. Cook the Chicken: Heat the olive oil in a large skillet over medium heat. Season the sliced chicken with Cajun seasoning, salt, and pepper. Cook the chicken for 5-7 minutes, or until cooked through and no longer pink. Remove from the skillet and set aside.

3. Sauté Vegetables: In the same skillet, add the diced onion. Sauté for about 3 minutes, until translucent. Add the minced garlic and cook for an additional minute until fragrant.

4. Make the Sauce: Pour in the chicken broth and bring to a simmer. Add the heavy cream and stir until combined and heated through.

5. Add Cheese: Gradually add the grated Parmesan cheese, stirring until melted and the sauce thickens slightly.

6. Combine Ingredients: Add the cooked chicken, cherry tomatoes, and spinach to the skillet. Stir well, allowing the spinach to wilt and the tomatoes to soften.

7. Incorporate Pasta: Add the drained pasta to the skillet and toss until coated with the creamy sauce.

8. Adjust Seasoning: Taste and adjust seasoning, adding more Cajun spice if desired.

9. Garnish: Serve hot, garnishing with fresh parsley for a touch of color and flavor.
