Wash asparagus thoroughly and break off the tough ends by bending it--it usually breaks when the tough and soft parts meet. Pat dry with a paper towel.
Place asparagus on a baking sheet, mix the remaining ingredients and pour over and mix to coat with the dressing.
Spread asparagus in a single layer and place in the oven.
Roast asparagus for 10-15 minutes, until tender but still crisp. (Vary the cooking time according to your preference).)
