Step 1

Add 2 tablespoons olive oil to a 12-inch deep skillet or sauté pan and place it over MEDIUM heat. Add the chopped chicken and cook, stirring frequently. Sprinkle chicken with Italian seasoning, a touch of salt, and fresh ground pepper, and continue cooking for 3 or 4 minutes or until chicken is completely cooked through.  Transfer the chicken to a plate and cover to keep warm. Add remaining olive oil to the pan and add the onions. Cook for 2 or 3 minutes, until softened and lightly browned. Add garlic and cook for a minute or two until fragrant.

Step 2

Add broth, tomatoes, pasta, crushed red pepper, salt and pepper and stir to combine. Stir in the cooked chicken and bring to a boil, cover skillet, and reduce heat to MEDIUM-LOW. Simmer until the pasta is tender, about 15 minutes. Stir in half and half and mozzarella and simmer for minute or two until warmed through and the cheese has melted.

Step 3

Remove the skillet from the heat and stir in the fresh spinach until it wilts from the heat of the pasta. Top with Parmesan and serve.
