Miso squash soup is a delicious winter dish inspired by the flavors of Asia. The sweetness of the squash compliments the rich miso to create a balanced soup. If you want to add a flavor booster, you might consider substituting vegetable stock for water. You will be able to find wakame (also known as seaweed) and dark miso in any Asian market and maybe even in your local supermarket. Miso squash soup is a dish you'll keep coming back to for Meatless Monday.
