Fry the onions and chilies(except chipotles) over a medium heat in a small quantity of oil until soft but not browned.
Add the garlic. Wait about half a minute and add the cumin and chipotle.
Wait another half minute and add the brown sugar, mix with the other ingredients, then add the tomitillos.
When the liquid starts boiling, add the beans and hominy and enough water to cover the ingredients (I usually eye ball it) but probably about 3/4 of the tomatillo can. Bring to a boil, then reduce the heat and simmer for at least a half hour, but longer is better.
Add salt to taste when it mostly done.
I like things hot, but you can make it with just 1 or 2 jalapenos and the bell pepper, or substitute your favorite chilies.
This goes great with your favorite vegan cornbread or tomalito.
