Variations:
Top each serving with a dollop of sour cream or yogurt. Sprinkle the soup with a small amount of grated orange zest. Substitute chopped chives or cilantro for the parsley. For a meaty soup, add 1 pound of raw lean hamburger or chopped sirloin steak, preferably from grass-fed cows, and combine with the vegetables and the lentils. Heat until the meat is thoroughly cooked.
