Florida Sunshine Shake

Peel and mash the ripe banana in a blender or bowl until smooth and free of lumps.

Pour the orange juice and grapefruit juice into the blender, then add the mashed banana.

Add the low-fat vanilla yogurt and vanilla extract to the blender.

Blend on high speed until smooth and frothy, about 1–2 minutes.

Divide the shake evenly among four glasses and serve immediately while cold.
