Make the Seasoning Mix and set aside.
Heat a large sauce pan or dutch oven on medium high. Once heated, add olive oil and butter. When butter has melted, add onion, green pepper, salt, and pepper. Sauté until softened.
Add ground pork and ground bison/beef and cook thoroughly. Drain any fat, if desired, using a spoon or meshed metal colander.
Add seasoning mix and stir to combine.
Do not drain the liquid from the tomatoes and red kidney beans, this adds flavor to the chili.
Add tomatoes, kidney beans, Hatch chili sauce, and tomato paste.
Simmer for about an hour.
Once chili is done, season the steak with salt and pepper; grill until it is medium rare. Let sit a few minutes.
Dice the steak into bite size cubes and add to the chili.
Garnish with shredded cheese, red onion, jalapenos, salsa, sour cream, and tortilla chips if desired.
Serve immediately.
