Add ice to the blender first and crush. Then add kale, mango, peaches, ginger, lime juice, and 1 cup water to start. The amount of water will depend on how many of your ingredients are frozen.
Blend until smooth, only adding water a little at a time as needed, and scraping down the sides and blending as needed.
Once your smoothie is well-blended, taste and make adjustments as you'd like. If it's too sour, add more fruit or a bit of maple syrup (optional). For more zing, add ginger. And for more acidity, add more lemon juice. To make it thicker or colder, add more ice and blend.
Divide between two serving glasses and enjoy immediately.
