Saw this recipe at the supermarket beside the asparagus and decided to
make it for lunch today. Not much bother to make and a nice flavour.
I left out the celery as I don't care for it and threw in some spring
onions instead.

Spring Asparagus Soup

1lb fresh asparagus, ends trimmed
1 tbsp olive oil
1 onion diced
1 carrot diced
2 stalks celery diced
4 cups chicken broth
Squeeze of lemon juice
½ cup finely diced Smoked Ham
1tsp salt - pepper to taste
2 tbsp of sour cream

Heat oven to 400deg. Spread asparagus on a baking sheet and drizzle
with olive oil. Roast on lower rack of oven until fragrant and lightly
browned, about 10 minutes.
Meanwhile in large saucepan, melt butter over medium low heat. Add
onion, carrot and celery, saute 5 minutes without browning.
Cut roasted asparagus into 2 inch lengths and add to saucepan along
with chicken stock and lemon. Simmer until vegetables are tender,
about 10 minutes. Meanwhile saute ham in a small skillet until
slightly crisp. Set aside.
Puree soup with hand held blender, or place in small amounts in
blender until smooth. Return to saucepan, season with salt and pepper
and warm until heated through. Transfer soup to bowls and garnish
with sour cream and ham.
