This simple-to-prepare soup really shines when asparagus is at its peak growing season. If you're making it during the winter, try substituting half the asparagus with broccoli for a more robust flavor.

In a large Dutch oven or soup pot sprayed with cooking spray, sauté onions over medium-high heat until translucent, about 3 minutes. Add garlic and cook 30 seconds. Stir in wine and cook until wine evaporates. Add broth, asparagus, and dill and cook 10 to 15 minutes, or until asparagus is tender.
Carefully puree soup in a blender or food processor until smooth. Return to pan and heat over medium-low heat until hot. Serve soup in warm bowls drizzled with olive oil.
