Well, all I am sure of is that watermelon is my favorite snack! I always grab a huge bowl of it at the grocery store. It’s so delicious and very hydrating too as watermelon is ninety or more percent water. Need a quick snack? Watermelon! Have a sweet tooth? Watermelon! Need hydration? Watermelon! That sweet, melt in your mouth texture and flavor. Yes, please! Is watermelon a fruit or vegetable? This website may answer the question for you.
