Super Juice?

I am going in a new culinary direction at this time I am trying some healthful recipes

Ingredients

1/2 bunch spinach
1 handful watercress
1/2 lemon, peeled
1 celery stalk
2 apples
1-inch slice of ginger

To make juice: In a fruit and vegetable juicer, juice all ingredients into a tall glass. Serve immediately.
To make smoothie: Prior to blending, chop apple and discard the core; peel and chop ginger; chop celery stalk; zest and juice lemon, throwing out remaining rind. Combine all ingredients, and blend on high until smooth. Add water or ice to help thin out the smoothie.
