In a medium sized skillet, cook the bacon until crisp, remove with slotted spoon and then set aside on a plate. Add the chicken, cook until brown and no longer pink. Set aside on the plate. Drain the remaining grease.
Add chicken broth, half and half, dry ranch seasoning mix to the skillet and whisk. Add the penne pasta and broccoli then bring to a boil and cover. Simmer for about 10 minutes or until the pasta is tender. Stir in the cheese and chicken and stir until cheese is melted and heated through.
