I tend to "wing it" with smoothies. I pop some fruit in and then add enough yoghurt or other liquid to reach the consistency I like on the day. So these amounts are approximate.
Two small bananas or one large one, sliced and frozen
Milk (cow, soy, whatever)--start with a cup and add as needed
One Tablespoon smooth peanut butter (preferably natural)
- Pop all of these in a blender.
- Blend until smooth, adding more liquid if necessary
