Warm the butter and olive oil in a wide skillet or saute pan and add the onion, garlic, bay leaves, thyme, and parsley. Cook over medium heat, stirring occasionally, until the onions have begun to color. Stir in the tomato paste, then add the wine. Bring to a boil and cook for 1 minute. Drain the lentils and add them to the wine with the water, and lightly salt. Return to a boil, then lower the heat, cover the pan, and simmer until the lentils are tender, about 40 minutes.
