Me too. What I did do is add a small turnip, I had in the frig and 1 stalk, minus the flowers buds of broccoli. The drink was very good. I rather enjoyed it. He does not give measurements so I made enough for just one and it was perfect.
I used:
1/2 bunch of coriander, parsley, arugula
2 inches of ginger
1/2 large lemon
1 apple
2 large cucumbers
1 tiny turnip
1 stalk of broccoli
1 pepper
