Preheat a 4 quart pot over medium high heat.
Saute the onion, green pepper and jalapeno in the oil with a big pinch of salt for 5 to 7 minutes, until onion is translucent.
Add the garlic, and saute until fragrant, about 30 seconds. Add the chili powder (start with 3 tablespoons and go from there), oregano, cumin, salt, pepper, and cloves and toss to coat the onions, letting the spices toast a bit (about a minute or so).
Add the 4 cups water and scrape the bottom of the pan to deglaze. Add the lentils, cover the pot and turn the heat up to bring to a boil. Let boil for about 20 minutes, stirring every now and again. The lentils should still be firm, but almost tender enough to eat.
Add the crushed tomatoes, kidney beans and black beans. Cover the pot, and turn heat down to simmer. Let cook for about 30 more minutes, stirring occasionally. The lentils should be quite mushy, almost melting into the chili. You may also need to add more liquid depending on how much the chili has cooked down. Adding up to two cups more would not be unheard of.
Add lime and maple syrup, then taste for salt and seasoning. It tastes best if you let it sit for 10 minutes or so, but if you can’t wait then just dig in!
