If you`re using canned beans you can skip this step. If you`re using dried beans, make sure to soak them over night (approximately 12 hours). The next day pour off the water you soaked the beans in and rinse off the beans.
Peel and finely chop onion and garlic cloves.
Heat oil in a pan or slow cooker, sauté onions for 2-3 minutes, then add minced garlic and sauté for another minute.
Pour the vegetable broth and add all the other ingredients, except the sweet corn.
Reduce heat to slow, cover the pan or close the slow cooker and let simmer for 5 hours. Please note: if you`re using canned pre-cooked beans the cooking time will be reduced to one hour.
Add sweet corn 30 minutes before your chili is done.
