Lentil Soup

Ingredients
2 tablespoons olive oil
1 cup finely chopped onion
1/2 cup finely chopped carrot
1/2 cup finely chopped celery
2 teaspoons kosher salt
1 pound lentils, picked and rinsed
1 cup peeled and chopped tomatoes
2 quarts chicken or vegetable broth
1/2 teaspoon freshly ground coriander
1/2 teaspoon freshly ground toasted cumin

Directions
Place the olive oil into a large 6-quart Dutch oven and set over medium heat. 
Once hot, add the onion, carrot, celery and salt and sweat until the onions are translucent, approximately 6 to 7 minutes. 
Add the lentils, tomatoes, broth, coriander, and cumin and stir to combine. 
Increase the heat to high and bring just to a boil. 
Reduce the heat to low, cover and cook at a low simmer until the lentils are tender, approximately 35 to 40 minutes.
Serve immediately.
