Add the tomatoes, oregano, and onion, and spices together in a food processor or blender. Blend until well pureed and blended.
Salt and pepper both sides of the pork chops. Lay them out in a pressure cooker.
Add the blended sauce over the pork chops in the pressure cooker. If using a dried sweet pepper, add it now too. Pressure cook on high for 10 minutes for thawed pork chops, or 17 minutes for frozen pork chops. Allow it to naturally release for 10 minutes.
When the pressure cooker and rice are ready, layer your plate with rice, then pork chop, then sauce, and scoop the refried beans on the side.
