When bananas are too ripe to eat, peel them, break them into pieces, and freeze them for smoothies later.

Mix in blender:

1. Several frozen banana pieces (1/2 to 3/4 of a large banana)
2. 1/2-3/4 cup frozen mixed berries
3. 1/4-1/2 cup plain yogurt
4. 1/3-1/2 cup (or more) juice, adjust for consistency
5. torn up raw kale leaves (maybe 1/2 cup?)
6. (flax seeds — optional)

Blend in blender until well mixed. Drink or eat with a spoon, depending on consistency.

Smoothies are certainly not calorie-free, but consider the ingredients. You get a lot of nutrition for the caloric content in one of these.

No, you can’t taste the kale. It just tastes like berry smoothie.

My favorite juices are cranberry-apple and pomegranate. The flax seeds add some texture.
