Wash and prep the bell peppers by slicing off the tops and removing the seeds. Spritz with olive oil spray.

In a skillet, sauté diced onion in olive oil until translucent, about 3-4 minutes. Add ground beef and cook until browned. Drain fat.

Stir in garlic, diced tomatoes, cooked rice, and seasoning, mixing well.

Stuff the peppers with the filling, leaving space for cheese. Top with shredded cheese.

Place stuffed peppers in air fryer at 360°F for 15 minutes until tender.

Sprinkle remaining cheese on top and cook for an additional 2-3 minutes.

Carefully remove the peppers, let cool for a minute, and serve.
