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

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

2. Prepare the Chicken: While the pasta cooks, cut the chicken breasts into bite-sized pieces. Season with Cajun seasoning, salt, and pepper.

3. Sauté the Chicken: In a large skillet over medium heat, heat olive oil. Add the chicken pieces and cook for about 5-7 minutes, until golden brown and cooked through. Remove the chicken from the skillet and set aside.

4. Sauté the Vegetables: In the same skillet, add minced garlic and sliced bell peppers. Cook for 2-3 minutes until the peppers are tender.

5. Create the Sauce: Pour in the chicken broth and heavy cream. Stir well. Bring the mixture to a simmer, then add the grated Parmesan cheese, whisking until smooth and creamy.

6. Combine Everything: Return the cooked chicken to the skillet, along with the halved cherry tomatoes. Mix well to combine all ingredients.

7. Add the Pasta: Gradually stir in the drained fettuccine, tossing until the pasta is coated evenly with the sauce.

8. Serve Immediately: Taste and adjust seasoning if necessary, then remove from heat.
