Cook the pasta according to package instructions.
Meanwhile, heat ½ tablespoon butter and 1 tablespoon olive oil in a skillet over medium heat.
Cook the sliced onion and bell pepper until soft, about 5 minutes.
Add the garlic and cook until the garlic is fragrant, about 1 more minute.
Add the flour and stir it around for 1 more minute.
Add ¼ cup of dry white wine to deglaze the skillet. Be sure to scrape up any browned bits that've stuck to the bottom of the skillet. Cook the wine for 1 minute to ensure the alcohol has burned away.
Add the chicken broth, basil and oregano to the skillet. Turn the heat up to medium-high until the broth boils, then turn to the heat down low and let it simmer for 5 minutes or so, or until whenever the noodles are done cooking.
Toss the noodles with the sauce, the shredded Parmesan, and the fresh herbs
Add the chicken on top of the pasta -- you might want to stir the chicken into the pasta and get it coated with some of the sauce.
