I would definitely cook the chicken first. Better yet, buy a whole roasted chicken and just tear it up and throw however much you want in to the soup. Bacon should also be cooked first. The cheese you can melt right in the soup. I would bring the broth to a very low simmer, then take a whisk and start stirring in the cheese. I usually use shredded cheese because it melts quicker. Don't add the other ingredients until the cheese has melted, or else you will get cheese clumps! LOL

Good luck, broth based soups are pretty easy and quick. Nothing like soup when you are sick
