Here are two I've been making a lot lately:
Morning juice
2 cucumbers
4-5 leaves of kale
4-5 leaves of romaine
1 small piece of ginger
1-2 broccoli stems (I love using these up!)
1-2 pears
4-5 stalks of celery
Whatever else I have on hand: some spinach, sprouts, etc.
Afternoon juice
1-2 lemons
4-5 carrots
1 small piece of ginger
1-2 apples
