For the vinaigrette: Combine the mandarin syrup, vinegar, canola oil, sesame oil, sesame seeds, ginger and ramen seasoning in a jar. Cover tightly with a lid and shake until emulsified. Hold in the refrigerator. Shake again before using.
For the salad: Preheat the oven to 350 degrees F. On a baking sheet, break up the ramen noodles into small pieces with your hands. Add the almonds and shake the pan to spread everything in an even layer. Bake until the ramen and almonds are a deep golden brown, 12 minutes. Let cool completely.
In a large bowl combine the romaine, broccoli, carrots, oranges and scallions. Toss with enough vinaigrette to lightly coat. Top the salad with the toasted ramen and almonds. Serve immediately.
