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.
