Step 1

Turn on a multi-functional pressure cooker (such as Instant Pot®) and select Saute function. Heat olive oil in the pot. Combine pork cubes, onion, garlic, chili powder, garlic salt, oregano, pepper, chipotle powder, and cumin in a bowl. Saute in the hot oil in small batches until pork is browned, about 5 minutes per batch. Turn off the pressure cooker.

Step 2

Add chicken broth, enchilada sauce, green chiles, and cilantro. Stir to blend. Close and lock the lid. Set cooker on high pressure according to manufacturer's instructions; set timer for 20 minutes. Allow 10 to 15 minutes for pressure to build.

Step 3

Release pressure using the natural-release method according to manufacturer's instructions, 10 to 40 minutes. Unlock the lid and add hominy, stirring to blend.
