In a large pot, cook the onion, garlic, and chipotle in adobo for 5-7 minutes, until they are soft and slightly browned. Use water to help scrape the browned bits off the bottom of the pot, if needed.
Add the cumin powder and cook for 1 minute.
Now, add the black beans, corn, red lentils, diced tomatoes, tomato sauce, and veggie broth. Cover the pot with a lid and let simmer, stirring occasionally, for about 25-30 minutes.
Once the lentils are cooked through, and the chili has reached the desired consistency, season it with salt and pepper. Add the fresh cilantro and lime juice now. Stir, and turn off the heat.
Garnish as desired. Some great garnish options are: avocado, lime slices, fresh tomatoes, cilantro, scallions, plant-based yogurt, crushed tortilla chips, or shredded lettuce. I also love to add a generous amount of my homemade Salsa Roja.
