One of the best investments I have made is my Vitamix. You can make hummus / bean purees, nut butters, soups and super quick and healthy smoothies. The Vitamix is very easy to clean as well. It is a quick process in the morning.
I really like kiwi smoothies. I buy kiwis in bulk at Costco because I get enough for a couple of weeks and they are inexpensive. Kiwis are high in Vitamin C and provide just the right amount of sweetness and acidity. My favorite smoothie is 2 Kiwis, 1 banana, a large handful of spinach, a handful of ice and 1/2 cup water. It is plenty sweet for me, but if you like it a bit sweeter, just add a few drops of blue agave. You can kick the nutrients up a notch by adding chia seeds and flax seeds to the smoothie. This will drive up the omega three fatty acids!
Just poor the smoothie in a travel mug and bring a handful of almonds in a zip lock to make your healthy breakfast-to-go complete.
