Strawberry Mac sounds good and it reminds me of a watermelon salad that I had at a friend's house. I've made several variations on it.
The original recipe is chunks of watermelon, slivered onions, chunked feta cheese, sprigs of mint, and an oil and vinegar dressing. The proportions of each are totally up to the cook.
I'm on the fence about the cheese, so I usually leave it out. I'm not wild about mint, so I swap it for dill or cilantro, but basil would also work. I season the oil and vinegar dressing with salt, black pepper, cayenne pepper, and powdered garlic. (I prefer fresh garlic most of the time and I'm sure it would be amazing in this dish, but it would also make the recipe all about the garlic. The powdered garlic stays in the background better, IMHO. Also the salt, ground black and cayenne peppers, and ground garlic seem to help the vinaigrette emulsify.)
I'm sure this would also be good made with other melons or a medley of them.
This salad is great the first day and arguably better on the second, after the flavors have blended, although this may be more true of my non-cheese version. It doesn't seem like feta would be happy in watermelon juice for very long. A
