In a large soup pot over medium heat, warm up the oil. When hot, add the onion and green pepper, and saute until they soften and the onion become translucent, about 6 minutes.
Add in the jalapeno and garlic, and stir for one minute more.
Add in the rest of the ingredients.
Bring the chili to a simmer over medium heat, then reduce the heat and simmer gently on low heat for 30 minutes.
Garnish with cilantro.
