You will be raiding your vegetable garden (or the farmstand or produce department) when you make this soup! And it is the shopping that takes the time. The soup itself is a breeze to put together. If you have homemade chicken broth, by all means use it. Otherwise, choose a good-quality canned broth, not too salty, so that the flavor of each of the many vegetables shines. And while we would like to suggest reserving this for the next day it is vegetable soup, after all, we don't recommend it. The orzo becomes waterlogged, and the vegetables are no longer al dente, either.
