There are all different ways to make a smoothie. You really can't mess it up. We use yogurt and milk. You could use only frozen fruit with soy or cows milk and skip the yogurt. My kids call this a mooothie. Below is the recipe I came up with for lunch smoothies.
1cup of fresh or frozen strawberries (or whatever your favorite fruit is)
1 cup of Stoneyfield French Vanilla Yogurt
1 cup of milk (or soy milk)
1 tablespoon of honey
1 teaspoon lemon juice (this is optional)
Throw it all in your blender...whizzer up. SERVES 2
You can substitute any fruit. Blueberries, raspberries, banana only, pineapple. You really can't mess it up.
Note:the lemon juice is only to help with any browning that may occur as the smoothie sits in your child's lunch. I also give my kids apple slices a little squirt of lemon juice in their baggie to keep them from getting brown, because then my picky kiddos won't eat them. Because OH MY they are brown!
Heck you may just want to give these to your kids for breakfast and skip the lunch thing.
Happy lunch making!
