Add thyme to the pan and cook until fragrant - about 2 more minutes.
Add all other ingredients (except sour cream and green onions) and bring to a low simmer.
Cover, and cook until tender.
Remove from heat and allow to cool slightly, Then blend until smooth. (I prefer using my immersion blender for this step, but you can also blend smaller batches at a time in your blender)
Dish into bowls and top with optional sour cream and green onions.
Enjoy! :)
