For the chipotle lime sauce, in a small bowl, whisk to combine sour cream, chipotle in adobo sauce (just the sauce, not the peppers), zest and juice of 1 lime and garlic powder. Store in refrigerator until ready to use. Can be prepared up to 4 days in advance.
In a large bowl, combine the ground turkey, green chilies, green onions, jalapeno, bread crumbs, chili powder, cumin, garlic powder, and salt. Divide into 4 equal pieces and stuff into prepared bell peppers.
Add 1 cup of water to the pot of the pressure cooker and place trivet inside. Arrange peppers on the trivet. An 8 inch perforated pan also works well for this.
Secure the lid and turn pressure release knob to a sealed position. Cook at high pressure for 15 minutes. When cooking is complete, use a natural release for 10 minutes and then release any remaining pressure.
Preheat broiler. Place bell peppers on a sheet pan. Top with pepper jack cheese and broil until browned and bubbly.
To serve: Pile on pico de gallo, chopped avocados, pickled jalapenos, and some crushed tortilla chips. Finally drizzle (or drowned) it in the Chipotle Lime Sauce.
Notes
Because the meat is cooked raw, a lot of juices will collect inside the pepper. Either drain into the pot after cooking or with a skewer, poke a hole in the bottom of the pepper before cooking.
