Any thin soup will help but there is some reason to believe chicken broth contains ingredients that also help. But if you don't like chicken or are tired of it, try beef or turkey or any thin, water soup. Spicy ingredients also help. Cayenne or chili peppers help clear the sinuses. Garlic has antibiotic and anti viral components and is an expectorant to help you cough up bacteria from your lungs.
Onion also has antiviral properties.
Bring two cups of water to boil. Dissolve chicken bullion cubes. Add cup diced potatoes or pasta. Add cup chopped chicken meat already cooked. Most cold sufferers don't feel hungry or want to cook.
