Maybe it's because I'm wishing I was in Key West, but this was my post run smoothie today, and it was awesome, nearly transporting me to an island far far away.
Key Lime Cherry Super Smoothie
4 key limes, peeled and seeded (or two regular limes)
large handful of spinach
2 tablespoons flax seeds
1/2 cup plain Greek, or other, yogurt
1 1/2 cups frozen dark sweet cherries
1/2 cup water
Blend like crazy. Drink immediately. Super tart and refreshing.
