Notes:
~ * Cilantro stems are edible and are actually the most flavor-packed part of the plant! They also give a nice little crunch as a soup topping.
~ ** If you use a regular blender, allow soup to cool a bit. then puree it in batches, otherwise you'll have a huge mess when you turn the blender on. I use a immersion blender (also known as a stick blender) for soups and lots of other things. They are very inexpensive and save a lot of time.
