If we weren't going out to dinner tonight, we might celebrate Earth Day with a bowl of green soup made with local asparagus.

This photo from Flickr member Dayna McIsaac inspired us. It looks like spring, and it reminds us of how a very few ingredients can create a fully nourishing meal.

We're not sure how the smoked flavor gets in there — perhaps by sautéeing the asparagus with a smoky ham hock or bacon? — but we do know that making a smooth vegetable soup is a piece of cake.

Follow our instructions for How To Make Soup from Almost Anything. With asparagus, we might add some heavy cream at the end.

Turns out we have quite a few green soups in our archives...

• Nettle Soup
• Spring Leek and Lemon Soup
• Zucchini Garlic Soup
• Creamy Leek and Yogurt Soup
• Easy Green Minestrone
• Easy Kale Soup For One (or Two)
