The one thing to know about this soup is that if you don't eat it right away the tortellini will soak up the liquid. So when you eat any leftovers you will want to add some more broth to the soup before heating it up. Oh, and you definitely want to use fresh tortellini because they cook much faster, taste better, and absorb less liquid. My favorite brand is Rana. * You definitely want to line your baking sheet with parchment paper when you roast the tomatoes. They roast more evenly this way and don't need to be flipped.
