Step 1

Preheat the oven to 400°F.

Step 2

Slice the peppers in half lengthwise and remove the seeds and membranes. Put in a baking dish face down and bake for 15 minutes.

Step 3

Meanwhile, heat the olive oil in a large skillet over medium heat. Add the onion and saute until translucent before adding the ground beef. Season with kosher salt and pepper and cook until browned.

Step 4

Remove the meat mixture with a slotted spoon and transfer to a bowl along with the cooked rice and red pesto. Mix until thoroughly combined.

Step 5

Remove the peppers from the oven and carefully turn them over. Stuff each pepper half with the filling until you have no more left (make sure to really pack it in there).

Step 6

Put the stuffed peppers in the oven and bake for another 15 minutes. Sprinkle with parsley and serve warm.
