Homemade smoothie mix. Duh, why have I not thought to do this? Just freeze yogurt in ice cube trays (will keep those big things of yogurt from going bad, too!), mix with some frozen fruit. Blend with milk when ready!
Food Pusher: Easy Homemade Smoothie: It didn't take me many trips to Jamba Juice to realize that I could work that same magic in my own kitchen. All I needed was some fruit, juice, yogurt, a tall cup, and an immersion blender and voila! Fresh homemade smoothies, any flavor I wanted, at a fraction of the cost of a Jamba Juice. Now, I realize, a lot of people don't mind paying for the convenience, but if I can make something comparable at home without too much trouble, I'm going to do it.
