1-First Step: Prep and cook the pasta (10 minutes)
* Bring a large pot of salted water to a boil. Use plenty of salt so the pasta itself is flavorful.
* Add 10 ounces short pasta and cook until al dente according to package directions (usually 8-10 minutes). Drain and set aside. Toss with a small drizzle of olive oil if not tossing immediately to prevent sticking.

2-Second Step: Season and sear the chicken (5-8 minutes)
* In a bowl, season 1.5 pounds boneless skinless chicken breast pieces with 2 tablespoons olive oil (or oil from sun-dried tomatoes), 3-4 minced garlic cloves, 2 teaspoons Italian seasoning, kosher salt, and ground pepper to taste.
* Heat a large skillet over medium-high heat. When hot, add the seasoned chicken in a single layer. Let sear undisturbed for 2-3 minutes to develop a golden crust.
* Stir and continue cooking for another 3-4 minutes until pieces are cooked through and no longer pink (internal temp should reach 165°F). Remove from the pan briefly if your pan is crowded, or continue in the same pan if there is space.

3-Third Step: Add sun-dried tomatoes and build flavor (2-3 minutes)
* Stir in 8 ounces sun-dried tomatoes (packed in oil, drained and chopped) and cook 5-7 minutes with the chicken so their concentrated flavor melds and the tomatoes warm through.

4-Fourth Step: Make the creamy sauce (3-4 minutes)
* Whisk together 3 cups 2% milk (or your chosen milk alternative) and 2 tablespoons gluten-free flour or cornstarch until completely smooth. This prevents lumps.
* Pour the milk mixture into the pan with the chicken and sun-dried tomatoes. Bring to a gentle simmer over medium heat and simmer for 3-4 minutes until the sauce thickens slightly. Stir frequently to avoid sticking.

5-Fifth Step: Add greens and cheese (1-2 minutes)
* Stir in 3 cups fresh baby spinach until wilted. The heat from the sauce will soften the leaves quickly.
* Remove the pan from heat and stir in 1/2 cup grated Parmesan cheese until melted and incorporated into the sauce.

6-Final Step: Combine and serve (1-2 minutes)
* Toss the cooked pasta with the chicken and sauce in the pan so every piece is coated.
* Serve immediately. Enjoy with extra grated Parmesan and a sprinkle of cracked black pepper if desired.
