Everyone has that one friend who pushes spinach around the plate and side-eyes anything with a vegetable in it. This is the smoothie we hand them, and it works every time. Green Machine looks like the healthiest thing on our menu, and somehow it tastes like a sunny fruit salad. We're not sure when the spinach got so good at hiding, but we're not complaining.

In the blender: mango, pineapple and banana doing the talking, with a solid handful of spinach and a little kick of ginger tucked in behind them. The fruit carries the sweetness, the ginger gives it that fresh, zingy edge at the end, and the spinach just quietly does its job. All you taste is bright and tropical.

It's also the cup we drink most ourselves, usually on the days when vegetables never made it anywhere near dinner. If you want your greens in Groningen without actually tasting them, this smoothie is the easiest way we know. Fair warning: the skeptics tend to come back for a second one.
