Hi Lori-
It varies, but my quick and easy go to is: 2 hands full of spinach and few leafs of kale, a frozen banana, soy or almond milk, a little raw honey, and a dash of vanilla.
It's really yummy and creamy.
When I have a little more time I prefer juicing my greens with green apples and grapefruits.
Everything else seems to take a little bit longer (especially because I feel the need to cleanup immediately after preparing).
