Lentils are the cheapest protein most grocery stores sell, and they are the only dried legume that needs no soaking. A one pound bag costs around a dollar fifty, makes about three pots of this soup, and keeps in the cupboard for a year. Brown and green lentils are the ones to buy for soup, because they hold their shape through a long simmer instead of collapsing the way red lentils do.
The step that separates a flat lentil soup from a good one takes sixty seconds. Before any liquid goes into the pot, the tomato paste, thyme, oregano and smoked paprika are cooked with the softened vegetables until they smell fragrant. Heat and fat pull the flavor out of dried herbs and concentrate the paste. Stirred into broth later, they stay raw and the soup tastes thin no matter how long it simmers.
The lemon juice listed as optional is the other thing worth not skipping. A pot of lentils and broth is soft and savory all the way through, and a spoonful of acid at the end is what keeps it from tasting heavy by the second bowl. Vinegar does the same job if there is no lemon in the house.
