Cook the pasta according to the package directions. While it cooks, melt butter in a skillet over medium heat and cook the onion and garlic till soft. Whisk in half and half and chicken broth. Stir in seasoned salt and mozzarella. Lower the heat to keep the sauce from boiling.
Add the chicken and red pepper slices to the sauce. Stir frequently and keep and eye on the heat so it doesn't boil. Drain the cooked pasta and stir it together with the sauce.
Add chopped parsley before serving.
Notes
This recipe calls for 12 ounces of roasted red peppers. We almost always used jarred mostly just because of how easy it is (you can see our favorite below), but you can use homemade roasted red peppers.Adapted from Eat At Home.
