In a pot, add 4 cups of water and set it to boil.
While the water is boiling, deseed and chop up the apple. Also, cut the broccoli florets and stem into pieces that would fit into the pot.
Add the chunks of apple and broccoli into the pot of boiling water. Let it cook for about 5 minutes. Set it aside to cool.
Blend to the broccoli and apple to your decided consistency. I prefer mind just a bit short of smooth. Season with salt to taste.
When serving soup, add a wedge of lemon to be squeezed in just before consumption.
