1 cup mixed berries, frozen*
½ banana, frozen**
1 cup spinach or kale
1 tablespoon ground flaxseed
1 cup water or coconut milk
Place all ingredients in a high-speed blender and process until smooth (about 1-2 minutes).
*If you want to use fresh bananas, add 4 or 5 ice cubes to the blender.
**When I have bananas starting to become over-ripe, I like to peel them, break them into chunks, and store them in the freezer to have on hand for smoothies.
