I've seen this a few times and it's been called everything from "Monster Smoothies" to "Popeye Smoothies". I think Pineapple Lime sounds more tropical :) And you really don't taste the spinach at all, it taste like a juice daiquiri!
In a blender put:
4 oz. water 4 oz. white grape juice concentrate 2 heaping cups of ice cubes 2 heaping cups of fresh baby spinach 1 pineapple wedge (see photo below) 2 limes (juice from two limes)
Blend until smooth, and serve immediately. So good, and what an awesome way to get some fresh spinach in huh! Especially for my toddler, or a pregnant lady like me who should be eating WAY more veggies than I am! :)
