Cut a thin slice from the top of each pepper, to remove the stem like a lid. Clean the insides of the peppers by removing the veins and the seeds.
Straightened the bottoms of the pepper carefully not to cut too much, just enough so they can sit straight.
In a large skillet over medium heat, add the ground beef, garlic, and onions. Cook until the meat is no longer pink and nicely browned. Drain any excess grease.
Add in the Worcestershire sauce, diced tomatoes, tomato sauce, and seasonings. Stir and simmer for 5-7 minutes.
Add in the cooked rice and mix until well combined.
Scoop the mixture into the peppers, filling them just to the top.
Air Fry for 10-12 min, top with shredded cheese, and air fry for 5 more minutes.
