I used one big banana, about the same volume of frozen peaches, two handfuls of spinach leaves, and enough water to get it blending, then a bit more water to smooth it into a drinkable consistency.
The ‘recipe’ says you can use any dark leafy green (i.e. kale) but that spinach was the least noticeable, taste wise. I have to say that seems true. I tasted the banana more than anything, and that was because it wasn’t quite ripe. I emailed Ande a photo and I’m sure she almost fell off her chair. This from me, the person who can live on toast and peanut butter, milk, cereal and chocolate. Heh.
