Place potatoes in microwave-safe bowl and cover with plastic wrap. Cook 5-8 minutes, stirring once. Allow to cool for a couple of minutes before removing from the bag. While potatoes are cooking, bring 1 quart of water to a boil in a medium saucepan.
Add asparagus to boiling water and allow to cook just a couple of minutes. Remove from heat, drain and plunge into cold water to stop the cooking process.
In a small bowl, whisk together all vinaigrette ingredients and set aside. Quarter the potatoes and slice asparagus into bite-size pieces. Add veggies to a large bowl and toss gently with vinaigrette. Serve warm or chill for 30 minutes before serving.
