Turn on Instant Pot to Sauté Mode and add 2 tablespoon of EVOO, then add bell peppers and onions.
Sauté veggies until soft, approximately 5 minutes.
Add cut up pork roast and ground pork, cook until no longer pink, stirring frequently.
Add garlic and sauté for 1 minute.
Add beer and deglaze bottom of pan by scraping up any browned bits.
Add chili powder, cumin, oregano, and bay leaves and stir.
Next, stir in remaining ingredients: tomato paste, canned diced tomatoes, pinto beans, taco sauce and tomatillos.
Press Cancel/Off button in Instant Pot.
Then, press Bean/Chili button in Instant Pot and cook. Once the pressure builds, the timer will come on and it will take 30 minutes to cook.
When it is done cooking, you can allow the pressure to slowly release, or you can release it by using the pressure release (venting) valve.
I like to let it slowly release for 10 minutes before using the pressure release (venting) valve.
Serve warm topped with cheese, avocado, and additional toppings of your choosing!
