Today I started with this:
2 cups raw spinach and lettuce mix
1 cup peaches
1 cup frozen blueberries
1 cup orange juice
And it tasted very "green." So I added more blueberries and some grapes. Better but still tasted a bit weird. Or maybe smelled a bit weird - like lettuce. It was ok, but not great.
Not sure where to go from here. We don't like bananas in smoothies. Maybe I'll go back to including yogurt. And I think I will stick to spinach for the green part!
