Lentil, split pea and barley soup with smoked turkey

Winter is at our doorstep, and with it comes days like today when the only reasonable thing to make is a huge pot of soup.  Here's my recipe for a delicious hearty soup.  You can easily make this vegetarian by omitting the smoked turkey wings.

1 Tbs. olive oil

1 C. diced onion

1 C. diced carrots

1 C. diced celery

1 tbs. kosher salt or smoked fleur de sel

1 tsp. black pepper

1 tbs. Italian seasoning

72 oz. chicken stock

1/3 C. each- barley, lentils and split peas, rinsed

16 oz. can diced tomatoes with herbs

2 bay leaves

2 smoked turkey wings

Optional- rind of Parmesan cheese

Heat olive oil on medium high heat in a large soup pot.  Add onion, carrots and celery.  Saute for 2 minutes, add remaining ingredients (including rind) and stir to combine.  Cover and simmer on medium low heat for at least an hour before serving.
