  • 2 tsp kosher salt
  • 1 pound lentils rinsed
  • 2 cans diced tomatoes with juice 14.5 oz cans

Notes

If you like creamy soups and you have an immersion blender, you might want to blend some or all of your soup depending on the consistency you prefer. I like mine chunky and don't blend it up. 
It's optional, but we also enjoy the added crunch of fresh chopped carrots and celery and always add some to each bowl before serving. 
To make this in a crockpot, add all ingredients except the lemon juice or balsamic vinegar to your crockpot and cook on high for five to six hours, or on low for seven to eight hours. 
Most of the time, when I buy lentils at the grocery store, the package is just identified as lentils, and it does not say what variety they are. These are most likely either brown or green lentils and either work in this recipe. 
When the soup is cooking, you might notice a scum bubbling up on top. You can remove this by taking a large spoon and skimming it across the top and then discard it. 
This dish will keep well covered in the refrigerator for up to five days. It also freezes well and can be stored in your freezer for up to three months.  
You can reduce the amount of sodium in this recipe by using low-sodium chicken or vegetable stock and low sodium diced tomatoes. If you use low-sodium ingredients, taste before serving and add additional salt if needed.
