Mix together salsa, garlic, green chilis, chili powder, salt, liquid smoke, cumin, paprika, and crushed tomatoes.
Add chicken, diced onions, and diced bell peppers to the bowl of the instant pot and pour salsa/spice mixture over the top (Or if you don't want to dirty that second bowl just pour everything one by one right in there! No biggie.)
Seal lid, close vent, push manual, and the up arrow to 12 minutes. It'll start on it's own.
When it's done, let it do it's natural release for 10-20 minutes until you can open the lid easily.
Pull out the chicken with a slotted spoon and shred in a different dish OR do what I do and throw it in your kitchenaid to mix until it's shredded. (I'm lazy.)
Throw it back in the pot, mix it into the juices and add in a handful of fresh cilantro and green onions.
Add 2 cups of chicken stock (you might want more if you want it soupier and less like chili) and 1 cup of frozen corn.
Stir- close the lid and keep warm until you're ready to eat... ten minutes or a few hours later!
