In a large pot or Dutch oven, heat 1 tablespoon of olive oil over medium heat. Add the diced green bell pepper and yellow onion, cooking until they are softened, about 5-7 minutes. Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.
Sprinkle in the chili powder, ground cumin, dried oregano, and smoked paprika. Stir well to coat the vegetables in the spices and let them toast for about a minute to enhance the flavors.
Pour in the can of whole tomatoes, breaking them up with your spoon as you add them. Follow with the vegetable broth. Stir everything together and bring to a gentle simmer.
Stir in the cocoa powder and 1 teaspoon of kosher salt. This ingredient adds a depth of flavor that complements the chili perfectly.
Add the chili beans (with sauce), kidney beans, black beans, pinto beans, and navy beans. Stir to combine all the ingredients and bring the mixture back to a simmer.
Reduce the heat to low and let your chili simmer for at least 30 minutes, stirring occasionally. This allows all the flavors to meld beautifully.
After 30 minutes, taste your chili and adjust the seasoning as necessary. If it needs more salt or spice, feel free to add it according to your preference.
Once your chili is well-seasoned and flavorful, ladle it into bowls and serve hot. Top with your favorite toppings like avocado, cilantro, or shredded cheese if desired.
