Bring a large pot of salted water to a boil and cook the pasta until al dente, about 8-10 minutes. Drain and set aside.
Heat the olive oil in a large skillet over medium heat. Add the sliced chicken breast and cook until golden brown and cooked through, about 5-7 minutes. Remove the chicken from the pan and set aside.
Add minced garlic to the same pan and sauté until fragrant, about 30 seconds. Then, stir in chopped sun-dried tomatoes and cook for another minute.
Pour in white wine (if using) and cook until it reduces slightly, about 2-3 minutes, while scraping any browned bits from the pan to add flavor.
Add heavy cream to the skillet, stirring until the mixture begins to thicken and coat the ingredients, approximately 2-3 minutes. Return the cooked chicken to the pan, stirring to combine.
Combine the cooked pasta with the sauce, tossing to evenly coat. Cook together for another minute until heated through. Season with salt and pepper to taste.
Serve hot, optionally garnished with fresh herbs or grated cheese. The dish should be creamy with visible pieces of chicken and sun-dried tomatoes, with a glossy sauce coating each strand of pasta.
