Healthy smoothie recipes?

1 cuo milk, 1 cup yogurt, 1 cup frozen blueberries, 1 medium frozen banana. Thick, filling, sweet & enormous -- fills two big glasses and then some.

I just posted this one elsewhere, but 1 frozen banana, 1 cup milk, bit of spinach, couple of drops of peppermint extract/flavour, 1tsp sugar/sweetener. The spinach makes it green & doesn't add flavour, it tastes like a shamrock shake!

Also 2tbls PB, frozen banana & milk. Bit more calories, but good for after a workout.
