Is watermelon good for meal planning?

Watermelon is over 90% water. It is one of the lowest-calorie foods per gram and very filling for the volume.

It works well as a hot-weather snack and pairs surprisingly well with feta or mint in a salad.

How to use watermelon in a meal plan

  • Cubed snack on hot days
  • Feta and mint salad with olive oil
  • Blended into a no-sugar agua fresca
  • Skewered for a fruit platter
