Heat 1 tablespoon olive oil in a large skillet set over medium-high heat. Add the chicken and cook until the chicken is no longer cooked in the center, stirring occasionally, about 5 minutes. Remove chicken from the skillet and set aside.
Heat 1 tablespoon olive oil in a large saucepan set over medium heat. Add onion and cook until the onion is soft and starting to turn brown, 4 to 5 minutes.
To the saucepan, add whipping cream, chicken broth, and water. Simmer, uncovered, for 8-10 minutes. Add green beans to the cream mixture. Simmer for 3-5 minutes, or until the green beans are tender crisp. Add red bell pepper and simmer for one additional minute. Add the cooked chicken to the cream sauce to reheat.
While the cream sauce and vegetables are cooking, cook 1 pound (16 ounces) farfalle pasta in a large pot of salted water until al dente. Drain the pasta and add it to the cream sauce. Toss to combine. Add flat-leaf parsley, lemon zest, and Parmesan cheese. Toss again to combine. Season to taste with salt and pepper. Serve immediately.
