A second try at a scrumptious chili with buffalo and chipotle because you know what they say: If at first you don't succeed try again...with less peppers.
Brown buffalo meat in a heavy bottomed pot over medium heat. Strain. Set aside.
To the same pot that you cooked the meat in add the olive oil and onions. Cook 3 minutes. Return the meat to the pan and add in the remaining ingredients. Mix well. Reduce heat to low and simmer uncovered for 2 hours.
