You can go without using oil if you are cooking broccoli rabe in the dry heat of a skillet. It adds a nice sear to the oranges as well. Seasoned with toasty sesame, this healthy vegetable side dish is an easy flavor upgrade.
Heat a large cast-iron skillet over medium-high heat. Place orange halves, cut-side down, in the pan and cook until browned and caramelized, about 5 minutes. Transfer the oranges to a plate.
Add broccoli rabe to the pan and cook, stirring occasionally, until it is blistered and the stems are tender-crisp, about 8 minutes.
Meanwhile, juice the oranges into a medium bowl. Whisk in oil, salt and pepper.
Add the broccoli rabe to the bowl and toss to coat. Serve garnished with sesame seeds.
