Not a success - Naya took two sips, opened her mouth wide in horror, then asked for an ice cube. Even I'll admit to a strange aftertaste:
Banana Ovaltine Smoothie
1 ripe banana (frozen or not)
1/3-1/2 cup skim milk or soy milk
1 tablespoon ovaltine
2 teaspoons non-fat vanilla or plain yogurt
1 scoop of non-flavored or vanilla whey protein powder (optional)
Place all the ingredients in the blender and blend until smooth. Makes 1 smoothie.
I shall persevere - one of my friends swears by ovaltine-based breakfast smoothies for her kids, and I think there may be something there!
