This is my favorite green juice recipe that Furman will also drink. Which says a lot. :)
1 large bunch of kale (washed and de-stemmed)
1/2 orange or clementine
1/2 inch of fresh ginger
1 tsp fresh lemon juice
I pour a little purified water through the juicer as I'm going which helps to keep everything moving and also makes it a little less intensely green.
