Preheat the air fryer to 400°F. Once preheated, add the cut peppers to the air fryer, spray lightly with cooking oil and cook for 6 minutes.
Heat oil in a large skillet over medium-high heat. Add diced onion to the pan and cook for 3-4 minutes, until softened.
Add in the minced garlic and cook for 1 minute. Next, add the ground pork and cook until browned, about 5 minutes.
Mix in the tomato sauce, spices, olive juice, rice and water. Stir and bring to a boil. Reduce the heat to low, cover and cook for 15 minutes or until the rice is cooked.
Turn off heat and stir in the olives. Spoon the mixture into the peppers and top them with cheese if using.
Place in the air fryer and cook for 6-8 minutes. Serve and enjoy!
Notes
If you prefer to use your oven, pre-bake the cut peppers at 400 degrees F for about 10 minutes. Cook the stuffing as normal, fill the peppers and bake uncovered for another 10-20 minutes.
These stuffed peppers can be stored in the fridge for 2-3 days covered in an airtight container. Reheat in the air fryer or oven for about 10 minutes at 350 degrees F. You can also reheat in the microwave for about 2 minutes.
If you would like to freeze the peppers, I recommend putting them in a freezer-safe bag or container. Store them for up to 3 months. Thaw them in the fridge overnight and reheat in the oven or microwave as stated above.
