Culinary Success: Lamb's Quarter Soup--a recipe

Sometimes the simplest recipes are the best! Yub Yub loves to make soup.  She says she is a soup expert, and every time we introduce her to a new wild green she asks to make soup from it.  Other than eating them as she picks, it is the only way Yub Yub will eat leafy greens.  This is a recipe she and I devised for lamb's quarters.   Our good friend recently visited from Miami and couldn't get enough of this recipe.

1 pound lamb's quarters, rinsed and chopped
2 tbsp butter
1 small onion, chopped
4 cups chicken or vegetable broth
salt to taste

1)  Melt butter in sauce pan.
2)  Saute onion in butter for 5 minutes.
3)  Add lamb's quarters and cook until wilted.
4)  Add broth.  Stir.
5)  Blend until smooth.
6)  Heat through and add salt to taste.
Enjoy!
