I have a Vitamix. This is what I have almost every morning.
Imagine the large plastic container of baby greens (Kale/spinach/chard). I take 1/2 of that and put it in blender. I smash it down until it is packed tight.
1/4 c of flax seeds (about 3 TBS)
1 banana
then I add water until it comes about an inch above the greens
Add whatever fruit is in the freezer (blueberries, pineapple, mango, blackberries, dark cherries)
Extras: peanut butter, ginger root, lemon
This usually makes 3 large containers that I drink throughout the morning which takes me through lunch.
