Tried (and liked) yesterday afternoon:
GREEN TEA WATERMELON-CUCUMBER COOLER
Makes 3 servings
In a pitcher, combine 1 bottle Lipton Natural Diet Green Tea with Watermelon (new flavor; also lovely on its own), 1/2 cup grated cucumber, and 3 oz vodka (optional). Let stand covered at room temperature 30 minutes; strain and chill until ready to serve.
Serve in ice-filled glasses garnished with cucumber slices and fresh mint leaves.
