pineapple strawberry yogurt smoothie

it seems like smoothies are quite the craze these days and you see recipes popping up everywhere.  i was looking at a magazine at work a couple of weeks ago and found a recipe that sounded pretty good so i tweaked it a bit and made one the next morning. 

pretty tasty if i do say so and it was rather filling!  it's a bit tart because of the yogurt, but all that protein really keeps the belly full, so it's worth it.  and, if you're turned off by the thought of spinach, it's hidden away so there is absolutely no flavor of it.

blend all of these together.

1/4 cup pineapple juice
1/4 cup strawberries
1/4 cup plain greek yogurt
1/2 frozen banana
handful of spinach
1/2 pack of splenda
