Adapted from the Green Eggs and Ham Cookbook by Georgeanne Brennan, this recipe serves 2-4.
1 cup frozen blackberries, thawed, or 1 pint fresh blackberries
1 cup skim milk
10 large fresh strawberries, green tops removed, or 1 cup frozen strawberries, thawed
2 scoops vanilla frozen yogurt or ice cream
Put the blackberries in a blender and puree them. Pour into two large glasses or a glass pitcher.
Put the milk, strawberries and frozen yogurt in the blender, and puree. Strain the mixture (optional; I didn't do it). Carefully pour the strawberry mixture on top of the blackberries, and serve immediately.
