Stuffed Peppers are a classic, healthy ground beef dish that can be easily made ahead of time and enjoyed by the whole family.
Preheat oven to 425°F.
Use a paring knife to cut a circle around the stem of the pepper and remove it. Cut the peppers in half from stem to end, creating 6 pepper halves. Place the peppers cut side down on the cutting board and gently tap them to loosen any remaining seeds.
Arrange them in a 9x13-inch baking pan, cut sides up. Drizzle the peppers with olive oil and sprinkle them with salt and pepper.
Bake for 20 minutes or until the peppers just begin to soften.
While the peppers cook, add the ground beef and onion to a large skillet over medium-high heat. Cook, breaking up the meat until the meat is cooked through, and the onions are softened. Drain off any excess grease.
Add in the garlic salt, chili powder, cumin, and oregano, and cook for another 60 seconds, or until the spices are fragrant.
Stir in the rice, and tomato sauce. Bring to a simmer and cook until the sauce thickens, about 1-2 minutes.
Stir in ¾ cup of the cheese until it melts.
Spoon the filling into the peppers and top with the remaining cheese.
Bake for 10-15 minutes until the cheese has melted and the peppers are tender. Garnish with green onion and serve.
