1. Preheat oven to 400 degrees. On a rimmed baking sheet, toss ramen with 2 teaspoons vegetable oil. Bake until golden brown, 5 to 7 minutes. Meanwhile, cut away and discard orange peels and white pith. Working over a large bowl, cut out segments and squeeze juice from membranes (you should have 3 tablespoons juice). Whisk in sesame oil, chili sauce, honey, and remaining 4 teaspoons vegetable oil. Season with salt and pepper. Add ramen and bok choy and toss.
