Instructions
Cook penne pasta according to package directions. Drain and set aside.
Season chicken with Cajun seasoning. Heat 1 tablespoon olive oil in a skillet over medium-high heat. Cook chicken for 5-7 minutes. Transfer to a plate.
Add remaining olive oil to the skillet and sauté bell peppers, onion, garlic, and jalapeños for 5 minutes. Remove from skillet.
Melt butter in the skillet, whisk in flour, and cook for 1-2 minutes. Gradually whisk in milk. Simmer for 2-3 minutes until thickened. Stir in Parmesan, salt, and black pepper.
Add pasta, chicken, and vegetables to the sauce. Toss to coat.

Notes
Adjust the spice level by using more or less jalapeños, or substituting with milder peppers like poblanos.
For extra flavor, use a combination of Parmesan and Asiago or Romano cheeses in the sauce.
Add a splash of white wine or chicken broth to the sauce for more depth of flavor.
Substitute shrimp for the chicken for a seafood version.
