For the pears, preheat the oven to 425 degrees F. In a small bowl, drizzle the pears with the olive oil, sprinkle with the sugar and salt, and toss to coat well. Transfer the pears to a baking sheet and roast for 10 minutes, until golden brown. Allow to cool.
For the vinaigrette, whisk together the olive oil, pecan oil, vinegar, honey, mustard, and shallots in a small mixing bowl. Season with salt and pepper.
To assemble the salad, combine the endive leaves and bitter greens in a large serving bowl. Add the vinaigrette and toss to coat well. Wait until just before serving to top with the pears, blue cheese, and pecans.
