Rinse the asparagus, pat dry and trim the ends. In a small bowl whisk together the olive oil, chili powder, garlic powder, salt, lime juice and lime zest.
Spread the asparagus on a baking sheet and pour the chili lime mixture over top. Toss the asparagus lightly and organize the spears to lay them flat.
Roast for 10 minutes or until bright green and browned slightly.
