That was QUICK. Hardly any time at all - you can prepare it in the morning to refrigerate all day, or you can just prep it and refrigerate it while you are fixing the rest of your dinner.
EASY, too. It really doesn't get any easier than this, which is a good thing with the lazy dog days of summer
Very CHEAP, also, especially if watermelon is in season and you have a mint plant.
And no question that it's very HEALTHY, as well. Most people think of tomato as the best source of lycopene, an antioxidant, but actually, watermelon often has even higher levels than the tomato. Mint is also another good cancer-fighter, and helps the digestive tract to run smoothly, easing stomach aches and settling indigestion.
