1/2 cup plain yogurt
1/2 cup milk
1 ripe banana
6 frozen strawberries
1-3 teaspoons sugar (or to taste)
Put all ingredients in the blender and mix until blended.
I actually don't measure the yogurt when I make this. I just put two BIG spoonfuls of yogurt in the blender and add milk to equal 1 cup. The banana should be ripe, because the sweetness means you don't need to add much sugar. Usually by Wednesday or Thursday the bananas I bought over the weekend are perfect, with little brown spots. You can use however many strawberries you want, too. The frozen strawberries give the smoothie that frozen texture. It's also very good with raspberries. It's a great breakfast!
