Preheat the oven to 400°F (200°C).
Prepare the oranges by peeling and segmenting them, then place on a baking sheet.
Drizzle the segmented oranges with a bit of olive oil and a sprinkle of salt before roasting.
Roast the oranges in the oven for 15-20 minutes, until they're caramelized.
While the oranges roast, wash and chop the kale into bite-sized pieces.
In a small bowl, whisk together olive oil, honey, balsamic vinegar, salt, and pepper to create the dressing.
Toast the walnuts in a dry skillet over medium heat for about 5 minutes.
Once the oranges are done roasting, remove them from the oven and let cool slightly.
In a large bowl, combine the chopped kale, roasted orange segments, toasted walnuts, and feta cheese.
Drizzle the dressing over the salad and toss gently to combine.
Taste and adjust seasoning if necessary before serving.
