Salmon on a Bed of Lentils

Heat oil in a Dutch oven or deep sauté pan over medium heat. Add shallots and garlic and cook, stirring, until softened, about 30 seconds. Add broth, lentils, onion, thyme, salt and pepper. Bring to a boil, reduce heat to low and simmer, covered, until the lentils are tender, 25 minutes. Add carrots and turnips; simmer until the vegetables are tender, about 10 minutes more. Remove the onion. Add more broth if necessary; the mixture should be slightly soupy. Taste and adjust seasonings. Lay salmon fillets on top, cover the pan and cook until the salmon is opaque in the center, 8 to 10 minutes. Serve in shallow bowls, garnished with parsley and lemon wedges.
