Preparing Southwest Chicken Alfredo is easy if you follow these steps:

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

2. Prepare the Chicken: While the pasta cooks, add the olive oil to a large skillet over medium-high heat.

3. Season Chicken: Cut the chicken breasts into bite-sized pieces and season with chili powder, garlic powder, cumin, smoked paprika, salt, and pepper.

4. Cook Chicken: Once the skillet is hot, add the seasoned chicken. Cook for about 7-8 minutes, until the chicken is golden brown and fully cooked through.

5. Add Vegetables: Stir in the corn and diced bell peppers, cooking for an additional 2-3 minutes until they are slightly softened.

6. Prepare Alfredo Sauce: Reduce the heat to low and pour in the heavy cream, stirring to blend. Gradually add the grated Parmesan cheese, stirring until melted and creamy.

7. Combine Pasta and Sauce: Add the drained fettuccine to the skillet, tossing to coat the pasta thoroughly with the sauce.

8. Final Seasoning: Taste and adjust the seasoning if necessary, adding extra salt or pepper to suit your preference.

9. Serve Immediately: Remove from heat and garnish with chopped cilantro if desired.
