Pineapple, kale and ginger make a delicious drink. That's a professional drink. I wouldn't have put them together, but the flavor is bright and exciting without being overly sweet. And without tasting anything like kale.
Mrs. HowChow stumbled on the smoothies when she wanted a snack on a trip to the Roots Market next door. We have had them a few times after an athletic Saturday morning. They're delicious. They're nutritious. You could almost justify $7 if the smoothie was your lunch -- although then you need to insist that they actually fill the cup, which hasn't happened every time.
Great Sage has a whole menu of smoothies with all kinds of fruit and even spinach. Pinapple and ginger has become my signature, but "Black Beauty" -- three kinds of berries and soy yogurt -- has other fans and may be my next try.
