Cook the Pasta:
In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente.
Reserve 1/4 cup of pasta cooking water, then drain the pasta and set aside.

In a large skillet heat, melt the 2 tablespoons of butter over medium heat. Add chopped onion and garlic and sauté until softened, about 3 - 4 minutes.

Add the halved cherry tomatoes to the skillet. Cook until the tomatoes are softened and starting to release their juices, about 5 minutes.

Add the diced chicken to the skillet with the tomatoes. Season with salt and pepper.
Cook until the chicken is browned and cooked through.

Combine Ingredients:
Add the cooked pasta to the skillet and toss to combine with the chicken and tomatoes. Pour in the reserved pasta cooking water and stir to combine. Season with additional salt and pepper to taste.

(Optional)
Stir in the chopped basil and half of the grated Parmesan cheese.
Enjoy!!!
