Cook rice according to package directions, making enough for 2 cups cooked (1/2 cup raw). Remove corn from freezer so that it has time to thaw.
Meanwhile, in a large non-stick skillet, over medium heat, begin to brown turkey. Add taco seasoning and stir to crumble meat; cook until no longer pink.
While turkey browns, dice tomato and avocado; chop onions, slice olives and shred cheese.
Place rice in the bottom of a cup, top with turkey and other desired toppings that were prepped. Serve each cup with diced watermelon on the side.
