In a skillet, heat oil over medium heat. Add onions and cook, stirring, until softened, about 3 minutes. Add garlic, cumin seeds, oregano, chili powder, salt and peppercorns and cook, stirring, for 1 minute. Transfer mixture to slow cooker stoneware. Add beans and stock and stir to combine.
Cover and cook on low for 8 to 10 hours or on high for 4 to 5 hours, until hot and bubbling.
Stir in cauliflower, jalapeno pepper, green pepper, Monterey jack cheese, and cream cheese and chilies, if using. Cover and cook on high for 25 to 30 minutes, until the green peppers are softened and cauliflower is heated through. Ladle into bowls and garnish as desired with chopped green onions and cilantro.
If you prefer thicker chili, mash some or all of the beans or puree in a food processor before adding to the recipe.NOTE: if you don’t have a slow cooker, you can certainly simmer this on the stove, stirring and adding liquid as needed
