Asparagus Topped with Creamy Tarragon Sauce
Bring 1 inch of water to a boil in a large saucepan. Put asparagus in a steamer basket, cover and steam until tender-crisp, about 4 minutes.
Meanwhile, whisk yogurt, mayonnaise, tarragon, lemon juice, water, mustard, salt and pepper in a small bowl. Drizzle the sauce over the asparagus. Serve warm or cold.
