This soup was created to accommodate a few of my dinner guests who were vegetarians. It was so good, we all enjoyed it. This can also be cooked on the stove for two hours at a low simmer. —Donna Marie Ryan, Topsfield, Massachusetts

Test Kitchen Tips
  • To quickly peel fresh garlic, gently crush the clove with the flat side of a large knife blade to loosen the peel. If you don’t have a large knife, you can crush the garlic with a small can.
  • You can convert slow cooker recipes to fit in almost any size crock—here's a helpful chart.
