Quick Tips : One Serving Smoothie

I'm really getting into smoothies lately. But the one thing I hate, is cleaning the blender, especially if I'm having more than one a day.

A couple of months ago, I came across this tip and it really changed things. I can't remember where I've read/hear about it, sadly. 

Here's the tip : a standard mason jar fits on a blender. So you put your fruits and everything in the jar, put it on the blender and then blend like normal. Then you only have the knives to clean. 

It's really good if your on the go or you don't want to have too many dishes to clean.
