In a large pot, cook pasta to al dente according to package instructions. While your pasta is cooking, make your chicken and sauce. Heat oil in a large skillet over medium heat and add in chicken.
Cook chicken until fully cooked, flipping when necessary to cook both sides. Add in the butter, garlic, chopped vegetables, and lemon juice. Cook until the vegetables are bright and start to become tender, about 4-5 minutes.
Add in the chopped basil and stir for another 30-60 seconds. If you want more sauce add in up to 1/4 cup of reserved pasta water to your sauce. Once the pasta is cooked and drained, add it to the skillet with the chicken and vegetables. Toss the pasta to coat it in the sauce. Serve the chicken pasta hot with extra fresh basil and parmesan cheese on top. Enjoy!
