Put everything in a large pot, bring to a boil, reduce heat, cover and simmer about 30-40 minutes. Remove bay leaf. Serve over brown rice (or maybe potatoes). Makes 4 reasonably sized servings.
NOTE: Use which ever vegetables you have on hand. Vary to suit yourself. leeks are great in this. If you'd want this to be more soup-like, add more water and a can of tomatoes, pureed.
