Drink all you like: there are no hangovers on this holiday.

We'll buy a jar of PB for National Peanut Butter Day, indulge during National Ice Cream Month and even throw in a few "arghs" for Talk Like a Pirate Day.

But when we heard that today is International Green Smoothie Day, we thought: that's a holiday we can really drink in.

To create the perfect celebratory sipper, we went to the pros at one of our favorite vegan restaurants, Blossom Du Jour, for its NYC Thrive smoothie. Grab the recipe here, or head to its café inside the Astor Place New York Health & Racquet Club for a cup.

Keep the festive mood with one of Blossom Du Jour's TRu Life Juice Cleanse packages--Vital Juice readers get 15% off during August and September.

Party on!
