This smoothie is simple to make and you can easily substitute any of the fruits out for whatever you already have on hand.
1 banana, cut in chunks
1 cup grapes
1 (6 ounce) greek vanilla yogurt
1/2 apple, cored and chopped
1 1/2 cups fresh spinach leaves
Place all ingredients into a blender. Cover, and blend until smooth. You may have to stop to push down anything that is stuck to the sides. Pour into 2 glasses and serve.
