It's an old book but still available on Amazon
This soup is so good!
My Favorite Lentil Soup
2 T olive oil
2 large / 3 medium onions, chopped
3 carrots, grated
3/4 t marjoram
3/4 t thyme
1 28-oz can tomatoes with juice
7 cups broth
1.5 cups dried lentils--rinsed and picked
1/2 t salt
1/4-1/2 t pepper
6 oz dry white wine
1/3 C fresh parsley or 2 T dried parsley flakes
Heat the oil in a large pot with a heavy bottom. Sauté the onions, carrots, marjoram, and thyme for about 5 minutes.
Coarsely chop the tomatoes, then add them to the veggies. Add the broth and lentils. Bring to boil, reduce heat, cover and simmer for a half hour to 45 minutes or until lentils are tender.
Add the wine after the lentils are tender, then season to taste.
I like to add chopped Kale near the end of the cooking time.
This soup is great topped with grated cheese
