Set oven to 400˚ F.
Chop to top off of the poblano pepper, remove the inside seeds and slice down the side to create two bowls.
In a large bowl, mix the bison, black beans, corn, tomato sauce, and dry ingredients together.
Fill each poblano pepper "bowl" with the mixture.
Bake peppers for 30 minutes.
Once the peppers have finished cooking, sprinkle with shredded mozzarella cheese. Alternatively, you can pull the peppers with 6-7 minutes left and add the cheese before place them back in the oven for the remaining time if desired.
Serve with cabbage, rice, or by themselves!
Store the remainder in the fridge and reheat or consume cold!
