Creating Chicken Pesto Pasta with Tomatoes and Pine Nuts is simple and straightforward. Follow these steps:

1. 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. Drain and set aside.

2. Sauté the Chicken: In a large skillet, heat the olive oil over medium heat. Add the diced chicken and season with salt and pepper. Sauté until the chicken is cooked through and golden brown, about 6-8 minutes.

3. Add Tomatoes: Once the chicken is cooked, add the halved cherry tomatoes to the skillet. Cook for another 2-3 minutes, until they soften slightly.

4. Combine with Pesto: Reduce the heat to low and add the basil pesto to the skillet. Stir gently to coat the chicken and tomatoes.

5. Mix in Pasta: Add the cooked pasta to the skillet, tossing everything together until well combined and heated through.

6. Add Pine Nuts: Lastly, fold in the toasted pine nuts for added crunch and flavor.

7. Serve: Remove from heat and transfer to serving bowls. Garnish with grated Parmesan cheese and fresh basil leaves, if desired.

These steps will guide you in preparing this incredible dish effortlessly. Each stage of cooking brings the wonderful flavors closer together, allowing the best elements of each ingredient to shine.
