This is the favorite soup at our house whenever anyone has a cold. We invented it over time, adding more spices as we went! The combination of the garlic, onion, ginger, chili pepper and cilantro really seems to give the immune system a boost. (But if you don't like one of these ingredients -- or don't have it on hand -- just leave it out; the soup will still taste good!) I prefer using leftover roast chicken for this recipe, but you can also use uncooked chicken -- just let it simmer in the broth until it cooks. And note: if you don't have lemon pepper, just use plain black pepper.
