Recipe from a restaurant called Iron Barley here in St. Louis. They say this recipe is for 2 dinner size entree portions. If you are going to serve it as a side dish it will serve 4, but they recommend you cut the watermelon in smaller pieces if doing smaller salads. Cooking time is actually marinating time. NOTE: I served just the marinated watermelon as a side dish (didn't put it atop greens nor did I use onions) and it was great with BBQ meat!!!
