Creating your own Monterey Chicken Spaghetti can be straightforward if you follow these simple steps:

1. Cook the Pasta: Boil a large pot of salted water, add the spaghetti, and cook according to package instructions until al dente. Drain and set aside.

2. Sauté the Chicken: In a large skillet, heat olive oil over medium heat. Add the diced chicken, seasoning with salt, pepper, and paprika. Cook until the chicken is browned and fully cooked, about 6-8 minutes. Remove chicken and set aside.

3. Sauté Onions and Garlic: In the same skillet, add chopped onion and minced garlic. Sauté until softened, about 3-4 minutes.

4. Create the Sauce: Add the diced tomatoes and heavy cream to the skillet, stirring well. Bring the mixture to a simmer.

5. Combine Ingredients: Return the cooked chicken to the skillet. Add in the cooked spaghetti, stirring until combined.

6. Add Cheese: Sprinkle the Monterey Jack cheese over the mixture and stir well to ensure it melts into the pasta and sauce.

7. Season to Taste: Adjust seasoning with additional salt, pepper, and Italian seasoning if desired.

8. Simmer: Let the dish simmer for 3-5 minutes until heated through and the cheese is fully melted.

9. Garnish: If desired, sprinkle chopped fresh parsley on top for a finishing touch.
