1 frozen banana, chunked
2 handfuls greens (lettuce, kale, spinach, etc.)
1/2 cup water
Place lettuce, banana, and water in Vitamix. Start with low speed (#1). Lightly tamper the greens toward the blades. It may help to tamper at the corners of the container before swirling the tamper throughout the container. Increase the speed to about #6 until the greens and banana have blended. Add additional water if necessary. If too much water is used, add ice cubes to reach desired icy consistency. Increase the speed to #10. Then turn the blender to high and super blend for 30 more seconds or until the mixture is smooth. Turn machine off and serve immediately.
This is the backbone to a lot of smoothies. The smoothie may be made sweeter by adding more fruit or mint. It may be made more savory by adding ingredients like cilantro or basil.
