Snap or cut off the woody ends of the asparagus spears. Then place spears in a shallow dish.
Add the dressing and toss to coat. If making dressing: just whisk ingredients together before coating the asparagus.
Spread the pears out in a single layer on a baking sheet. Bake for 9-10 minutes (narrow spears) 10-12 minutes (fat spears). Then toss in pan and return to oven to bake for another 8-9 minutes.
Plate, season with salt, and serve.
