Green "Fridge" Soup

Every couple of weeks, especially during fall and winter, I will make a fridge soup; an opportunity to clean out bits of vegetables that are not looking so good or not enough for a meal. So this week my fridge offered ends of asparagus, green beans, and bok choy. Trow in onions, some garlic and one potato for thickening, some herbs and spices, puree everything,  and the result, this time, was quite green! Quite tasty and good for you to boot.
