This humble and hearty combination makes a satisfying main dish, especially on a cold night. Lentils are an excellent source of folate and molybdenum, and a very good source of dietary fiber, protein, and manganese. Any type will work here.
02While the lentils are simmering, cook the cabbage with the remaining onion and garlic in a wide lidded skillet. Heat the remaining tablespoon of olive oil over medium heat and add the sliced onion. Cook, stirring often, until tender, about 5 minutes. Add 1/2 teaspoon salt and the garlic and stir together until the garlic is fragrant, about 1 minute. Add the cabbage and turn the heat to medium-high. Cook, stirring, until the cabbage begins to wilt. Add 1/4 cup water, turn the heat down to medium, cover and simmer 10 minutes, or until the cabbage is tender and sweet, stirring from time to time. Add salt and freshly ground pepper to taste.
03Spread the cabbage over the bottom of the pan in an even layer. Top with the lentils and potatoes. Sprinkle on the parsley, and serve in wide soup bowls. Sprinkle with Parmesan if desired.
