What do you need to make smoothies?

You put into a blender: up to a cup of mixed fruit chunks, about 2 T frozen OJ concentrate, enough water so it will blend, about 1/4 c of plain yogurt, 1 envelope of Splenda. If you want a different taste you can use almond milk instead of the yogurt, and reduce the sweetening. Blend in the yogurt or almond milk last with the Splenda. You can also put in oatmeal powder (grind in a blender). Frozen fruit chunks can be frozen unsweetened fruit such as strawberries, blueberries, blackberries, raspberries, bananas cut about 1-1/2 inches, mango, peaches, etc. Just one banana chunk helps give a smooth texture without overpowering banana taste. Any fruit combination that you like: strawberry, banana, blackberry with yogurt - or banana, peach, oatmeal powder, almond milk. Don't skip the OJ concentrate though; it adds a lot of flavor. Using frozen fruit means you don't have to use ice cubes - if you use unfrozen you need some ice cubes.
