Creating Southwest Alfredo Penne Pasta is easy and rewarding. Follow these steps to make your meal shine:

1. Cook the Pasta: In a large pot of salted boiling water, cook the penne pasta according to package instructions until al dente. Drain and set aside.

2. Sauté Vegetables: In a skillet, heat olive oil over medium heat. Add the diced green bell pepper and red onion, sautéing until soft, about 3-4 minutes.

3. Add Chicken: Incorporate the cooked chicken breast into the skillet, stirring to combine. Cook for an additional 2-3 minutes to heat the chicken through.

4. Prepare the Sauce: Pour in the heavy cream, ensuring to mix well. Gradually add Parmesan cheese, stirring continuously until the cheese melts and the sauce thickens.

5. Season the Sauce: Sprinkle in chili powder, cumin, and garlic powder, stirring to evenly distribute the seasonings. Add salt and pepper to taste.

6. Combine: Gently fold in the cooked penne pasta, allowing it to absorb the sauce completely. Heat through for 1-2 minutes, ensuring everything is well-mixed.

7. Add Salsa: Remove the skillet from heat, then gently mix in the salsa, ensuring that it blends with the creamy Alfredo sauce.

8. Serve: Transfer the pasta to large serving bowls. If desired, garnish with fresh cilantro and serve with lime wedges on the side.

These steps will guide you in creating an incredible dish that boasts both flavor and comfort.
