I have almost the same thing for breakfast every morning. I always have one of two smoothies: either one made with a banana, some sort of frozen fruit, vanilla soymilk, and flax seed; or one made with a banana, peanut butter, chocolate soymilk, and flax seed. Even before becoming vegan, a morning smoothie was my preferred breakfast because it's easy, delicious, and filling. When I became vegan I tweaked the recipe by adding protein powder - either vanilla or chocolate, depending on the smoothie I'm making.
About a month and a half ago I further perfected this routine by purchasing a cuisinart blender that came with four to-go cups, so you can blend your smoothie right in the cup. Voila - an even faster, on-the-go breakfast!
I've even gotten my boyfriend in the habit. Now, instead of heading off to work with nothing, at least I know he's had a little something to start his day. Plus it's a little extra protein in his diet, which I'm sure every growing boy needs :)
