1 cup fresh blueberries
1 (6- to 8-oz.) container low-fat or nonfat blueberry yogurt
1 to 1.5 cups blueberry or orange juice
1/4 tsp. vanilla extract, or a pinch of cinnamon
Wash the berries. For an icier, colder smoothie, freeze the berries in a single layer on a cookie sheet until partially frozen, about 30-45 minutes. Place the berries in a blender with the yogurt, juice and vanilla. Blend on low speed until ingredients are just mixed, then switch to high school and blend until smooth.
