half a ripe avocado
1 to 1.5 frozen bananas
4-5 frozen or fresh strawberries
splash non-fat soy or other nut milk
pinch cardamom
pinch allspice
whatever else strikes your fancy; nuts, fruits, spices, etc.
Throw all ingredients into a blender and blend until desired texture is reached. I prefer it smooth, but some like a chewable drink. Very, very delicious!
