Slice the peppers lengthwise, then remove the stem and seeds. Place on a baking sheet that has been lined with parchment paper for easy clean up.
Place peppers in the oven for 12 minutes to roast.
In a large skillet, over medium heat, cook the ground beef breaking it up into small pieces as it cooks. Cook until no longer pink.
