Thick, creamy Greek yogurt takes the place of the usual mayo-and-cream cheese medley you'd find in traditional spinach dip. It provides all the wonderful richness that you would expect, only in a much healthier way. Serve this with thick-cut raw veggie slices like carrot, cucumber, jicama, or radish for easy scooping. Or, slather a spoonful of this creamy dip on top of a piece of cold poached chicken or salmon. It's also delicious folded into an egg-white omelet for a hearty hello to start any day. If you want to play around with this recipe, you could use arugula or watercress in place of the spinach for a peppery bite or quickly-blanched kale for a change of pace.
