Smoothies are a super easy way to add whole fruit and some vegetables to a diet. Smoothies are far superior to fruit juice in that they contain less sugar and retain the fiber that helps fill us up, among having other health benefits.
A few years ago a friend of mine passed on a recipe for a smoothie that had been developed specifically to get a child to eat raw spinach. It was a complicated recipe that involved tofu, mango juice, and sweeteners. I tried it for myself, and it did taste fantastic. I have since experimented with simpler smoothie recipes. I've found that raw spinach can be added to just about any fruit smoothie, and it will not ruin the flavor - no sweeteners or exotic juices are necessary. These days I just throw together a smoothie based on whatever I happen to have on hand, but it occurs to me that I should start a collection of the most successful attempts. So here I present a much simpler version of the smoothie that got me started. Again, the taste of the spinach is so mild that it really gets lost, and the only evidence of its presence is the green color, which as you can tell from the photo, my kid doesn't mind one bit:
