1. Bring a large pot of salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Drain and set aside.
2. In a large skillet, heat the olive oil over medium heat. Add the diced chicken, seasoning with salt, pepper, and Italian seasoning. Cook for 6-8 minutes, until the chicken is golden and cooked through.
3. Add the minced garlic to the skillet with the chicken. Sauté for about 1 minute, until fragrant.
4. Toss in the broccoli florets and pour in the chicken broth. Cover and steam the broccoli for 3-4 minutes, until tender yet vibrant green.
5. Reduce the heat to low, then pour in the heavy cream. Stir in the Parmesan cheese, allowing it to melt into a luxurious sauce.
6. Add the cooked pasta to the skillet, tossing everything to coat. If you like a little kick, sprinkle in some red pepper flakes.
7. Let the pasta simmer in the sauce for 2-3 minutes, allowing the flavors to meld beautifully.

For a little extra flair, finish off with a sprinkle of fresh parsley or basil, if you have it on hand.
