We go through quite a bit of spinach when making smoothies in our Vitamix. It is full of nutrition and is considered one of the "magic vegetables" since the taste "magically" disappears when you blend it with fruit and other smoothie ingredients. We throw a handful of spinach in almost every batch of smoothies we make. Fresh spinach can be frozen for later use in cooking or smoothies. (Just don't expect to make a salad out of it.) I just rinse the spinach, spin it in the salad spinner, and pop it in a zipper freezer bag.

"Green Monster" is a term that can be used for just about any smoothie that contains green vegetables. Here's a recipe for a basic green monster that our family enjoys.
Green Monster
1 1/4 cup diluted juice (apple, white grape, pineapple, almost any juice will do OR use 1/4 cup juice concentrate plus 1 cup water)
1 orange, peeled (leave the white pith)
1 slice pineapple, 3/4" thick, skin removed
1 banana, peeled, fresh or frozen cut into chunks
1-2 cups spinach (1-2 big handfuls)
1-2 cups ice
Add ingredients to the Vitamix in the order listed. Start on variable speed 1 and quickly increase to variable speed 10, then switch to high for one to one-and-a-half minutes.
