Trim woody ends from asparagus and rinse.
Steam asparagus in microwave safe dish for 3 to 6 minutes till tender. The thicker your asparagus, the longer it will take to cook.
In a small mixing bowl, combine the salad dressing, mustard, stevia, and lemon juice.
Finely mince half of the lemon zest and stir it into the sauce. Reserve the rest of the zest for garnish.
Plate a serving of the asparagus and drizzle the sauce over the top. Sprinkle a bit of lemon zest or julienned carrots on top and serve while the asparagus is still warm.
