I add a partial leaf of collard greens, swiss chard and kale to my fruit smoothies. You never know
they're in there if you have flavors from your fruits. I add just a tiny bit of bilberry juice, black cherry concetrate, pomegranate juice, coconut milk, most of my juice is herbal tea or distilled water. Lately I've just been using a tiny piece of banana, about 5 strawberries, a handful of blueberries, a nice chunk of papaya (I can't get enough of it lately)and whatever else flavor I want to add that day, either grapefruit and orange section, or cantelope and muskmelon, or mango, etc.
I put a scoop of whey protein powder and a piece of avocado.
