Lentil Stew

I have kind of perfected this recipe of mine.  It's so healthy that it is surprising that it tastes so darn good!  If you want to make it more of a soup, just add more broth.

1 large vidalia onion, chopped
2 cloves garlic, minced
1 large sweet potato, peeled and cubed
1 large zucchini, cubed
1 large red pepper, chopped
olive oil
salt & pepper
1/2 bag red lentils or small green lentils
1/2 jar marinara sauce or 2 cans diced tomatoes
approximately 4 cups vegetable broth

Saute onion and garlic in olive oil for a few minutes in a large pot.  Once they begin to soften, add the sweet potato and red pepper and saute just a few minutes before adding the zucchini.  Saute a few minutes more then add the tomato sauce and the lentils.  Stir well then start adding vegetable broth.  You should add enough so that the lentils are submerged plus maybe another inch.  Stir well, cover and bring to just a boil.  Reduce heat a bit and let simmer for about 40 minutes until lentils and all veggies are soft.  Be sure to watch the liquid content as it cooks, you may need to add a bit more broth here and there.  Adjust the seasoning by adding salt and pepper if needed at the end.
