Place a non-stick pan on medium heat and add in a drizzle of oil. Add in the ground beef, onion, and garlic. Fry for 5 minutes until the beef turns a light brown. Break apart the beef mince, we don't want any big chunks.
Then, add in the cumin, paprika, chilli powder, dried oregano, salt and pepper. Stir to combine.
Preheat the oven to 190c fan or 210c / 375F. Add the rice, the black beans, and the passata to the ground beef pan. Stir to combine. Then set aside while you prepare your bell peppers.
Slice the bell peppers in half lengthwise and remove the seeds and placenta.
Stuff the pepper halves with the filling. Delicately arrange the peppers into your oven-proof dish or tray and top each pepper with cheese. Place into the oven, covered in kitchen foil for 30 minutes, then uncovered for another 15 minutes.
Once the bell peppers are slightly charred and the cheese has melted, remove from the oven and leave to sit for a couple of minutes. Then top them with sour cream, jalapeños, and lime. Enjoy!
