You may have noticed a high amount of sodium on the nutrition label. The nutrition label pulls data from the USDA nutrition database which uses a store-bought version of the vegetable broth (which tend to be high in sodium) when it calculates nutrition amounts. I usually try to make my own vegetable broth, which will be much lower in sodium! I'd suggest making your own to lower the sodium in this recipe or finding a "low-sodium" broth in store to use.
