Chop the onions, garlic & veggies. Sauté in a large pot or dutch oven, using a little vegetable broth (or water).
Sauté for a few minutes and add the spices of your choice ... I added cumin, paprika and chili flakes. Add tomato purée. You will start smelling the fragrance of the spices.
Add kidney beans, corn, tomatoes, lentils and two cups of water.
Let everything simmer for 30-45 minutes. Stir frequently. Add more water if necessary. Lentils may take a little more time to cook.
While the chili cooks, roughly chop the dark chocolate. Add chopped chocolate to chili along with sea salt and pepper. Add other optional items if you wish.
Garnish with more chopped chocolate and a dollop of yogurt, parsley or cilantro.
