Heat 2-3 tbsp of broth in a pot over medium heat. Add bell pepper, onion, and garlic. Saute for 3-5 minutes until the onions start becoming translucent. Then add lentils, crushed tomatoes, and the rest of the broth.
Bring the contents to a boil. Add the spices, salt, and maple syrup. Stir and cook over medium-high heat for 15-20 minutes. Make sure the pot is covered with a lid. I recommend stirring your chili every few minutes.
Next, add the corn kernels and cilantro, and cook for another 10 minutes. Remove the chili from the heat, add the almond butter, and stir it in. Taste and adjust seasonings as needed.
