Green Smoothie

This healthy smoothie is delicious and nutritious and the spinach isn't overpowering.

1 banana, cut in chunks
1 cup grapes
1 (6 ounce) tub vanilla yogurt
1/2 apple, cored and chopped
1 1/2 cups fresh spinach leaves

Place the banana, grapes, yogurt, apple and spinach into a blender. Cover, and blend until smooth, stopping frequently to push down anything stuck to the sides. Pour into glasses and serve.
