I like to switch my breakfast up from time to time and I have developed the Chunky Monkey. This is great for when I want a bit more substance or am out of key veggies in my Green Monster.
1c chocolate soy milk
1c of ice, less if crushed
about a 1/4 c of chunky peanut butter (or your favorite peanut butter)
1 large banana
Blend in the vitamix until smooth
Now if you do not have chocolate milk or if your beautiful Little Fellow has drank all the chocolate soy milk, plain or vanilla work fine. I suspect dairy milk would work as would almond milk or even rice, although the rice milk I think would make it thinner. Depending on how ripe the banana is, you may need to add a tiny bit of honey. Also if you are out of chocolate milk, but have chocolate peanut butter handy, that works perfectly too...
I know you are all thinking-- wowza that is alot of peanut butter, but honestly, this is my breakfast. Generally my go to breakfast if lunch is going be several hours later. Also, I am not doing grains, so I am finding it takes more to fill me up. Adjust to suit your needs.
