This is one I eat most mornings.
1/3 peeled cucumber
1/2 small avacado
juice of 1/2 lemon
juice of 1/2 large or 1 small grapefruit
1/3 can coconut milk -- probably could substitute with yogurt, ricotta, etc.
small handful of spinach leaves
Blend. It's surprisingly good. The grapefruit juice provides just enough sweetness to make it quite pleasant. The individual tastes of the avacado, cuke and spinach all disappear into green goodness.
Another I like a lot:
sm handful of spinach or swiss chard or even kale
water to cover -- tho for the protein you might use some or all milk or yogurt, or ricotta as well as the water
Blend. Quite delicious. Both of these are outstanding ways to get VEGETABLES inside you!
