Paleo (eating like our pre-agricultural revolution ancestors ate) chili is made without beans. In the west we typically include beans, but I think even non-paleo eaters will enjoy this deep smoky flavorful chili. This is best made a day ahead so the flavors can meld together. Serve with green onions and sour cream.
This chili can be enjoyed by non-Paleo eaters by adding 1 (15 oz.) can of drained and rinsed pinto beans.
You can substitute beef for the bison and turkey sausage for the pork sausage.
